Ni-Cr-Mo alloy system- Special family of Nickel based alloys


The most versatile alloys in Nickel based alloy matrix is Nickel-Chromium-Molybdenum alloy. The presence of chromium and nickel offers resistance to oxidizing and reducing acids and also act as synergistically to offer great resistance to chloride induced cracking of pitting, crevice and stress corrosion cracking. Other families are nickel-chromium-iron and nickel-iron-chromium that are made to bridge the performance and cost gaps between the Nickel-Chromium alloys and austenitic stainless steels. Their advantages over stainless steels including better resistance to stress corrosion cracking.

Nickel-Chromium-Molybdenum alloys are specifically resistant to insidious and variable forms of corrosion resulted by chlorides, pitting, crevice, and stress corrosion cracking. Chromium causes passivation in oxidizing acids as it occurs in the stainless steels. Molybdenum offers resistance to reducing acids specifically to hydrochloric acid. In heat exchangers, not just steam is essential, in fact cooling medium is also considered. Cooling waters are usually chlorinated to combat biofouling and sea water is used as a coolant at various coastal locations.

As Ni-Cr-Mo alloys prevent hydrochloric acids and related salts, they also prevent the related compounds of bromine and fluorine. Actually Ni-Cr-Mo alloys are one of the metallic materials that withstand hot hydrofluoric acid. They resist sulfuric and phosphoric acids and specific contents of caustic soda and caustic potash.

Hastelloy C
Hastelloy C-276- It was made by introduction of argon-oxygen decarburization during melting
Hastelloy C-2000- Copper was added to alloy C2000 for resistance to sulfuric and hydrofluoric acids.

The effect of tungsten in Ni-Cr-Mo alloys is similar to Molybdenum.
NiCrMo alloys are basically face centered cubic structure. They are similar to austenitic stainless steels. They are not fully stable and are hence sensitive towards the production of second phases when subjected to temperatures in about range 650oC to 1100oC.

The NiCrMo alloys are usually supplied in the solution annealed form, the annealing temperature for many alloys is about 1120oC. They are usually cooled in water from their annealing temperatures to lock in their high temperature fcc microstructures. Although they are cooled in gas if they are annealed in hydrogen.

At low temperature limits, a homogenous, long range ordering reaction is feasible however this is slow and of no worry during welding. Nickel alloy Hastelloy C22 wire was designed particularly to take benefit of the long range ordering reaction in a time length of 48 hours with just a moderate reduction in its corrosion functionality. The development of cast Nickel-Chromium-Molybdenum alloys has followed a similar path with initial efforts followed at enhancing heat stability and where feasible improved corrosion resistance. The nickel-chromium-molybdenum alloys are usually supplied in the solution annealed condition, the annealing temperature for many alloys is around 1120oC. They are usually cooled in water from their annealing temperature to hold their high temperature fcc microstructures. 

Concerns over structural instability are extreme during welding, since weld heat affected regions are subjected to temperatures in the sensitizing limit. The second phases of many concerns are M6C carbides that develop in the limit 650 – 1040oC and micro-phase that occurs in the limit 760oC to 1090oC. These phases develop quickly and differently usually within the alloy grain limits, leaving them to be sensitive to preferential corrosion.

From mesh clothes through elements to complete systems


A great range of materials are used in weaving mesh clothes. To determine the most suitable material, the physical properties of the material are evaluated. It is complemented by experience received from applications in various industries and processes. Finally the feasibility of testing the cloth in lab and technical center and through wide trials at the customer site.

From the different methods in which metal wire mesh clothes, specific weave have proved themselves in specific to be fit for filtration.

As specific sintered wire mesh cloth materialsare found for fit for specific filtration applications, they are precisely manufactured, specifically high quality for durability and long lifetime. It is complemented by the particularly wide practical knowledge that Heanjia experts always want to share with you. The close interaction and sharing knowledge between customers and company has continually proved itself as the basis for significant improvements.  

Commonly used weave types
Plain Weave- It has natural origins in braiding. Whether it be willow rods or metal wires – they are interwoven. There are several ways to do this. As a result, the family of plain weaves is fully diverse with respect to appearance and structure.

Plain Dutch Weave High Flow- It is woven in the same way as the basic plain dutch weave, receives the tag- High Flow for allowing the high flow rates that are enabled by the shute wires that are made thinner than usual which actually doubles the openings.

Twilled Dutch Weave- Considering the plain weave, the weft wires of the dutch twiiled weave are organized as close together as feasible. Although this weave has double the count of weft wires as compare to plain dutch weave. A very small aperture is developed by three weft wires that cross in different directions and combining with warp wires, make a channel which is open on two sides.

Reverse Plain Dutch Weave- In this weave type, the warp wires are kept thin and weft wires are relatively thicker simply just opposite of the standard dutch weaves. The reverse dutch design develops specifically pore opening that run in an angle to the mesh surface. The large count of warp wires significantly increase the active filtration cross section. Following the specifications, it can be about 21-25% to offer RDW filters with an excellent contamination retention potential.

Reverse Dutch Twilled Weave- It is an important weave type where warp wires are relatively thin similar to normal reverse dutch weave. The difference is the twilled weave pattern of the weft wires that means the warp wires are not as highly deformed and physically stressed as for example that happens in plain weaves. The strength of this weave is its perfection for applications that deal with large levels of mechanical stress.

You can discuss with our engineers about everything of mesh be it a specific material for wire cloth, semi-finished product or component or the need to create a complete screen. The specialists at Heanjia and our customers has led to a large number of long term and promising business relationships.

Corrosion resistance performance of Hastelloy C22 Grade


For a long time corrosion resistant materials like Inconel 625 and Hastelloy C276 have offered wide corrosion resistance for equipments in chemical, power production, pollution control, marine and various applications. The reason of the development of chemical products and enhanced processes is the new challenges that have encouraged the development of Hastelloy C-2000 and Inconel alloys that are widely being used to prevent corrosion and safeguard product purity in conditions beyond the capability of stainless steels or other materials. These alloys offer several benefits including increased life cycle cost performance, better reliability, lower maintenance and reduced downtime costs.
Presence of nickel, chromium, molybdenum and other elements is essential for various applications where severe corrosion resistance is needed. Chromium prevents corrosion in oxidizing media while molybdenum enhances resistance to reducing media. Presence of chromium and molybdenum maintains the stable austenitic single-phase structure. It is essential in receiving suitable corrosion resistance in an alloy capable of being economically made and produced.

Hastelloy C276, Hastelloy C22, Inconel 625 and Hastelloy C2000 are evaluated for corrosion resistance and how their performance varies with changing acid temperature, concentration and mixture. It is seen that alloy Hastelloy C22 wire and Hastelloy C276 offer great flexibility and versatility in preventing corrosion in a great range of environments.

Localized Corrosion Resistance
Localized corrosion attack is one of the commonly occurring failure mechanisms of stainless steels and high Nickel-Chromium-Molybdenum alloys. This kind of localized corrosion attack is normally less predictable as compare to general corrosion and more limiting to a materials performance. Pitting Resistance Equivalent Number can be calculated by using chemical composition to estimate relative pitting resistance of alloys. Hastelloy C22, Hastelloy C2000 are completely resistant to pitting and crevice corrosion up to the temperatures of 85oC.

Seawater
Corrosion rates for Nickel-Chromium-Molybdenum alloys in marine conditions are very nominal in flowing and stagnant media. High nickel alloys are extremely resistant to stress corrosion cracking in water based chlorides that may otherwise affect the lower alloyed stainless steel 300 series. Nickel based alloys with a PREN number more than 40 are highly resistant to crevice corrosion in marine water. Although in tight crevice conditions for example in seawater cooled plate heat exchangers that have multitudes of tight crevices, high alloyed materials for example Hastelloy C22 and Hastelloy C276 are needed. Inconel 625 and Hastelloy C276 have offered significant performance in seawater service.

Inconel 625 with a PREN above 40 is commonly used as wrought and weldmetal in preventing seawater corrosion. This material is widely used as a weld overlay on carbon steel components as an affordable way of enhancing performance in corrosive conditions. Although high alloyed weldmetal with larger PREN values find uses in severe seawater service conditions.

High temperature seawater

Crevice corrosion tests are conducted in high temperature natural seawater at 60oC for 60 days in stagnant conditions. The test medium was chlorinated with 1-2ppm free chlorine to simulate service conditions usually used in offshore oil and gas industry seawater service. Hastelloy C276 and Hastelloy C22 were found to be fully corrosion resistant in these conditions.

Stress corrosion cracking in oil refineries


Stress corrosion cracking occurs due to combined corrosion and straining of a metal as a result of residual or applied stress. It create a remarkable loss of mechanical strength with nominal metal loss that can cause mechanical fast fracture and catastrophic failure of components and structures.
SCC is not a predictable process and for many metals in diverse conditions it doesn’t occur.  Therefore engineers try to use materials more efficiently by increasing work stress and using economical materials. Commonly used alloys for SCC systems are- Carbon steel, low alloy steel, strong steel, austenitic stainless steel, duplex stainless steel, martensitic stainless steel and copper alloys such as Monel 400 wire excluding Copper-Nickel alloys.

Oil refineries
Aqueous hydrogen sulfide in oil and gas development applications can create various challenges. H2S is a harmful gas that can cause vigorous metal loss corrosion and catastrophic brittle fractures of pressurized equipment and pipes. These brittle cracks on metallic structures can occur fast with nominal to no signs or may take a long time to be visible.

Sulfide stress cracking is cracking of a metal due to combined action of tensile stress and corrosion in availability of water and H2S.

Monoethanolamine is an absorbent used to eradicate acid gases comprising of H2S and CO2 in oil refining units. Recent damaged in various refineries have described that cracks can be parallel or normal to welds based on the orientation of basic tensile stresses. Cracking has been found to be both transgranular and intergranular.

Postweld stress relief of carbon steel weldments in MEA units was performed only when the metal temperature of the equipment was assumed to exceed 65oC and the acid gas comprised of above 80% carbon dioxide or when the temperatures were assumed to exceed 95oC or 200oF in any acid gas content.

Presently any system comprising of MEA at any temperature and at any acid gas content is postweld stress relieved. It is the result of studies performed on various refineries to define the level of SCC problem in this media. These inspection programs showed that leaks were widespread and were discovered in vessels that had been postweld stress relieved. Additionally, it was discovered that the whole concentrations of MEA were included and the most concentrations of MEA were often at comparatively low temperatures. Systems found to experience cracking included tanks, absorbers, carbon treater drums, skimming drums and pipes.

Materials used in oil refinery units have to be competent enough to perform in the various conditions for production environments and designs. They should be strong yet ductile enough to prevent brittle fractures. Alloy’s composition, yield strength, hardness, heat processing, microstructure, fluid pH, partial pressure of H2S, total applied tensile stress, cold work, temperature and time are the main factors that have an influence on deciding whether or not SCC will occur to a specific metallic structure.


The recommended alloys to use in oil refineries are Hastelloy C276, Monel alloys and Inconel alloys. These alloys offer seamless and long term performance against vigorous corrosion of SCC. So contact us to order your alloy today.

Advanced production technique for Inconel alloy 718


For a long time NASA has been making efforts in developing Electron Beam Freeform Fabrication (EBF) for developing net shape metallic components that offers benefits for suitable streamlined production of intricate components with its ability to directly deposit materials on any area where it is required. Many markets want to use this technique to improve the material application efficiency by preventing the need for machining large magnitudes of materials from wrought blocks and forgings or the development of high detailed molds for castings.

By using EBF process for the development of Inconel 718 components for use in high temperature structural applications is analyzed. Inconel 718 is a commonly used superalloy for offering good weldability that makes it suitable for the EBF process. The mechanical characteristics of EBF deposits and the potential to customize these characteristics to specific applications are also evaluated. Thin walls were made like that the wall thickness consisted of width of an EBF deposit bead. Following layers were deposited on each other to develop the wall builds. Additionally a bulk deposit was made by developing several layers of many side-by-side EBF deposition passes.
The EBF system uses a high power electron beam gun in vacuum. The feedstock wire is supplied from spool by following wire feed mechanism. The gun and wire feed are installed on a gantry with the potential of translating back and forth with single axis.

Inconel 718 wire and plates were used for EBF wall and bulk block.

Experiment
The sample plate was configured at four corners to the EBF system support table. An electron beam gun preheated the base plate and eradicated the surface oxides in the vicinity of the wall and block built before deposition.

Two walls were made on the same base plate. During the wall development, four single pass beads were deposited on top of each other then the system was cooled for two minutes.

Tensile samples were machined from the two wall builds that were oriented in a way that the sample length was parallel to the wall length. Some samples machined from the block build were heat processed o find the influence of after-EBF heat processing on the characteristics and microstructure.
HT1 heat treatment for wrought Inconel 718 included- heating up to 1750oF for 60 minutes then air cool to room temperature, heating up to 1325oF for 8 hours then furnace cool to 1150oF and heating up to 1150oF for 8 hours then air cool to room temperature.

HT2 heat treatment for Inconel 718 castings included- heating up to 2175oF for 4 hours then air cool to room temperature, heating up to 1325oF for 8 hours then furnace cool to 1150oF and heating up to 1150oF for 8 hours then air cool to room temperature.

Results

No Inconel 718 alloy components were vaporized to any level during the e-beam production process. Tensile characteristics of two walls produced at dissimilar deposition travel rates were similar. Ultimate tensile strength and yield strength showed significant difference from sample to sample.  Modulus for wall builds was considerably lower than traditionally processed Inconel 718.

Wire mesh for heat exchanger components


Wire Meshes are open cell structures with low weight and density, high permeability and good heat conductivity that make them suitable for a great range of industrial applications including fluid and heat flow. Thermal spray coating processes were used in the production of advanced high temperature stainless steel heat exchangers.  Stainless steel wire mesh heat exchangers were modeled by connecting the tube to the wire mesh through wire arc thermal spray coating that offered suitable connections between the wire mesh and tube’s outer surface and has potential to replace costly brazing or other metal connection methods.

There have been innovations in increasing the efficiency of combustion and reaching stoichiometric AFR made by many companies across the globe, although some companies have tried to recover the heat of the combustion. By positioning a heat exchanger box above the hot gas stack, the heat of combustion can be captured. Although it is hard to produce heat exchangers that can withstand high combustion temperatures and have a sufficient efficiency to make them commercially feasible.

Waste gases exit flares at temperatures above 1000oC that exceeds the service temperature of most high heat conductivity materials like copper and aluminum that are normally used to develop heat exchangers. High efficiency heat exchanger design can compensate for the low heat conductivity of materials for example stainless steel and Inconel that can withstand high temperatures.
Heat transfer through a heat exchanger depends on its geometry and thermal properties. The magnitude of heat that passes through a material is based on thermal conductivity of the material. To increase the efficiency and functionality of heat exchangers, the chosen material should have high heat conductivity.

Heat exchangers are made to transfer heat between two fluids that are at different temperatures while keeping them separate from each other. Design of heat exchangers varies based on application however it often involves convection in both fluids, conduction in the separation wall and radiation.
Compact heat exchangers are normally used because of their large heat transfer surface area to volume ratio that is named area density. This large surface area is often received by connecting fins to the wall separating both fluids with the fluid with low heat flow coefficient flowing on the fin side of the wall.


Tungsten wire meshes are commercially available in a great range of sizes and there are also several wire orientations popular in the industry. Metallic wire meshes are porous materials comprising of different metals in square, rectangular and round hole shapes. Wire mesh screens are made in different pore sizes, wire diameters and wire types. They are also classified depending on the connection type between the wires such as woven, crimped and others. Woven wire meshes are made in different pore densities. For effective fluid flow and heat transfer performance of wire meshes, mesh pattern and shape are highly significant. Wire meshes have been used in tube heat exchangers to improve heat flow in a similar way to solid plate fins, additionally their porosity also reduces the pressure drop.

Major applications of Nickel Base Super alloys


Superalloys are heat resistant alloys containing nickel, nickel-iron and cobalt that have a combination of mechanical strength and resistance to surface degradation. Actually,  it is basically used in gas turbines, coal conversion plants and chemical plants and for other specialized applications that need heat and corrosion resistance. A significant characteristic of nickel base alloys is their use in load-bearing applications at temperatures above 80% of their incipient melting points, a part that is more than for any other type of engineering alloys.

Nickel base super alloys are the most complex and commonly used materials for the hottest parts and for many metallurgists, these are most attractive super alloys. Presently they contribute more than 50% weight of advanced aircraft engines. The major properties of nickel as an alloy base are the high phase stability of FCC nickel matrix and capability to be reinforced by various direct and indirect sources. Additionally, the surface stability of nickel is enhanced by alloying with chromium and aluminum.

The major use is in the development of gas turbines for application in commercial and military aircraft, power production and marine propulsion. Superalloys find common applications in oil and gas plants, space vehicles, submarines, nuclear reactors, military electric motors, chemical processing vessels and heat exchanger tubes. Many generations of super alloys have been made for higher temperature resistance.

High temperature applications of super alloys
The high temperature applications of super alloys are wide such as in aircraft, chemical plants and petrochemical plants. Additionally super alloys are commonly used in aerospace and marine plants, nuclear reactors, heat exchanger tubes and industrial gas turbines. In F119 engine that is a latest version of military engines to power high performance aircrafts. The gas temperatures in these engines in the hot areas may increase to levels above 2000oF. Quenching methods decrease the real component metal temperatures to lower levels and super alloys that can serve at these limits are the major components of hot regions of these engines.

Aero and Land Turbines
The super alloys offer high temperature creep and fatigue resistant non-rotating applications that involve lower stress levels as compare to rotating components.
Turbine vanes and other static non-rotating components are widely designed with low coefficient of thermal expansion and high thermal conductivity. With prolong service life, land based casting specifications are becoming more complicated.

Surgical Implants
Nickel based alloys have high strength with good ductility and corrosion resistance and bio-compatibility. The alloy implants are developed by casting, forging and powder metallurgy. The alloys are used for orthopaedic implants such as artificial hips and knees.

Gas Turbine Engines
Superalloys are widely used in gas turbine engines that serve at high temperatures and need high strength, good creep resistance and good corrosion and oxidation resistance. In turbine engines this is in the high pressure turbine where blades can serve at temperatures reaching if not over their melting points.

Oil and gas plants

Nickel based super alloys have wide applications in oil and gas industry that involve corrosive and challenging media. Nickel based alloys Inconel 718 wire is commonly used in oil and natural gas development.

Hot corrosion behavior of super alloys



Different tests have been conducted to evaluate hot corrosion. Immersion testing that was the initial lab test method, is not considered reliable for simulating the gas turbine conditions. The salt coated method is very popular to study corrosion mechanisms. Engine manufacturers although use the burner rig test system to determine relative alloy functional ranking. The rig burns fuel with extensive air to develop combustion gases with continuous injection of a synthetic sea salt solution. This kind of test system shows the best lab system for simulating the gas turbine environment.

Hot corrosion resistance of different nickel and cobalt base alloys at temperatures from 870oC to 1040oC with 5ppm sea-salt injection. A good correlation between alloy functionality and chromium concentration has been seen. With increase in chromium content in alloy resistance to hot corrosion is improved. Alloys with 15% chromium or less are prone to hot corrosion. Cobalt based alloys are normally better than nickel based alloys. It may be because of higher chromium concentrations in cobalt base alloys. Hastelloy alloy wire with chromium content similar to cobalt base alloys was noticed to behave similarly to cobalt base alloys.

Burner rig tests were performed at 900oC or 1650oF on various wrought super alloys and nickel aluminides. The combustion gas stream was produced by using fuel oil comprising of 0.4 wt% sulfur with an air to fuel ratio of 35 : 1 and injection of 5 or 50 ppm sea salt in the combustion gas stream. The samples were loaded in a carousel that moved at 30 rpm during testing to ensure that all samples were subjected to the same test condition. The samples were cycled out of the combustion gas stream once every hour for two minutes, during which time the samples were quenched by forced air to less than 205oC or 400oF.

Superalloys analyzed were Hastelloy X, alloy 25 and alloy 150. The test results at 900oC for 200 hours with 50 ppm sea salt suffered extensive hot corrosion attack after 200 hours at 900oC with 50 ppm sea salt being injected into the combustion gas stream. Scanning electron microscropy with energy dispersive x- ray spectroscopy analysis described that nickel aluminides attained porous nickel or nickel rich oxides with nickel sulfide penetrating through the remaining metal. A secured chromium rich oxide layer was developed on alloy X.

Alloy 25 attaining nominal weight change, showed proof of initial cracking of chromium –rich oxide layer. SEM/EDX studies showed the development of cobalt-rich oxide nodules on the outer oxide layer on alloy 25. This showed the beginning of the breakway corrosion for alloy 25 after 200 hours at 900oC with 50 ppm sea salt. Prolong test outcomes under the same test condition clearly described that alloy 25 experienced extensive hot corrosion in excess of 200 hours of testing.

High temperature or hot corrosion normally occurs in the temperature limit of 800 to 950oC. It is trusted that molten sodium sulfate deposit is needed to begin hot corrosion attack. Another kind of hot corrosion is featured by pitting attack with little or no internal corrosion underneath the pit. Cobalt base alloys are more sensitive to such corrosion that normally includes Na2SO4 and CoSO4. Hastelloy X showed excellent performance in these media.

Metallizing wire coating for successful and prolong performance of industrial components


Metallizing wire coating is done through melting and projecting the molten wire material on a substrate. Different thermal spraying processes used to apply these coatings include different methods, devices and heat sources. The spray materials are commonly used in wire or rod form. With the passage of material through spray unit they are heated to a molten or semi-molten state and then atomized or accelerated and carried to the substrate in this form.

The heating is performed by gas flame, electric arc, plasma or detonation of a combustible mixture. The hot particles are conveyed from the spray system to the substrate through the gas jet that also accomplishes the atomization and particle acceleration.

Woven Wire Mesh Applications in industrial and chemical plants


Wire mesh has uniform geometry and pore size so the material flow-through can be accurately specified. It shows supreme characteristics for filtration and separation of solid, liquid and gaseous media. So the wire mesh is fit for draining, sizing solids, filtering and cleaning fuels, hydraulic fluids, water purification and processing and homogenizing molten polymers.

Wire mesh included in filters cover a great range from ultra-fine micron structures to coarse structures. Mesh offers special benefits over other filter media as it allows more uniform filter service as compare to other filter sources with easier cleaning.

While choosing the weave type, material, mechanical, chemical and physical characteristics are also considered with the service requirements. However not visible at the first glance, the mesh filter media meets its function in several areas of application. For instance while filtering or treating water, sea water and waste water and treatment plants. Flow regulators direct fresh water to flow from the tap cleanly, clearly and normally.

When filter elements are made from woven wire mesh they become excellent for offering high strength, stability and chemical characteristics. They retain contaminants like scrap that is essential when encasing the wire cables. Additionally they also ensure the essential homogeneity for uniform viscosity.

Machines, motors and hydraulic systems all serve best when grease and cooling fluids like transmission oil are filtered by metal woven wire filters. The wire filters offer suitable service for office and household equipments. Nozzles in inkjet printers offer suitably sizes and filtered ink particles, dishwasher filter offer a clean supply of water and clean the wastewater. Our woven wire mesh based filters are also used in medical industry in the cleanroom environments.

We also develop filter mesh for inhalators, breathing and dosing system and blood analysis units. These need ultra high quality components delivered under the highly stringent quality procedures. We produce metal wire mesh filters to ensure flawless service of control units and engines in aviation and aerospace, clean air from air-conditioning units and clean fuel at the fuel stations. Woven wire mesh is used in a diverse range of applications in the automotive industry such as inlet screens for aluminium casting, air filters for pneumatic units, mesh for bearings, mesh filters for exhaust treatment units and fuel lines. Fuels are optimally distributed by wire mesh and electric contacts are activated.

Monel Wire mesh is used in chemical industry such as for liquid chromatography, or as a filter media for producing medicines and various other products.


The strength of wire, material type, hole size and weave type describe the wire mesh structure. It can be relatively open while having supreme stability. It is particularly fit for different applications including the security of elements without influencing its performance. Wire mesh can even improve the service level of the application. General applications include headphones and microphones where the mesh secures the sensitive parts from mechanical knocks while allowing the sound flow to develop suitable acoustics. There are also several other applications of mesh screens on the industrial scale. Contact our engineers to know more.
