Which are the major applications of C276

Hastelloy C-276 exhibits excellent corrosion resistance in different kinds of harsh environments. With several applications such as ducts, stack liners, heat exchangers, scrubbers, stack liners, evaporators, and reaction vessels, the industrial dependence on this alloy is known widely. This alloy finds application in different industries such as power generation, chemical and petrochemical processing, pulp and paper production along with pharmaceuticals, and wastewater treatment.

Corrosion resistance of Hastelloy

C-276 is one of the universal corrosion resistant materials available today and used in strong and oxidizing and reducing conditions. The only thing that limits the use of this Hastelloy is the low chromium content that does not make it suitable for environments containing hot nitric acid. With exceptional resistance to hydrochloric acid, acid chlorides, formic and acetic acids, and solvents, and chlorine solutions, industries rely on this alloy for several applications.

Treatment – fabrication and heat

This alloy can be formed using various hot and cold working processes. The tendency to work harden can be cold formed using the harsher methods that are aggressive as well such as press forming, deep-drawing, and punching. The hot forming process is to be carried at extremely high temperatures. Annealing of the material if to be carried out after hot forming and the temperatures should high here as well.

Choice of an incinerator for waste treatment

Incineration is a prominent waste treatment procedure that helps in the treatment of waste by converting all the inorganic materials into water vapor and carbon dioxide when exposed to high temperatures. Incinerators are extremely useful as they help in the destruction of all those substances that are potentially harmful, and are used for the treatment of industrial, toxic and municipal waste. Various substances are present in the waste materials such as sulfur, brominated compounds, fluorocarbons, and chlorinated organics. These components are oxidized at extremely high temperatures inside the incinerator resulting in the formation of nitrogen oxide, sulfur oxide, and hydrogen halides which make it difficult to choose the right material for the incinerator. However, C276 is one of those superalloys that can be chosen as the material for the incinerator.

Industrial applications of C276

What exactly is the reason for choosing C276 as one of the most reliable materials for the incinerator? The systems used in the process of incineration are often subject to high cycles of temperatures, and the acidic condensate leads to corrosion. The sheet, plate, and pipe materials made from this Hastelloy C276 can perform at oxidizingtemperatures ranging about 1900 degrees Fahrenheit making it the right choice for an incinerator. Due to the presence of molybdenum, nickel, chromium and a bit of tungsten, this material shows high resistance to corrosion and is the right choice for equipment that is used for the treatment of wastewater.

With the ability to resist a high amount of chlorides when compared with the rest of the alloy, it is used in pitting and crevice corrosion, general corrosion, and stress corrosion cracking. The material also finds use in the processing industries due to its capacity to weld easily, and low carbon content reduces the carbide precipitation during the process of welding thereby making it just right for resisting the intergranular attack.
