Hastelloy Bar- Highly anti-corrosive & weldable

Hastelloy is a family of alloys such as C-22 & C-276 that is widely used for its high corrosion resistance. Hastelloy C-22 alloy is a nickel-chromium-molybdenum-tungsten alloy that is highly versatile due to its high resistance to both uniform and localized corrosion along with various mixed industrial chemicals. Hastelloy C-22 alloy has excellent weldability and is used as overalloy filler wire and weld overlay consumables to increase resistance to corrosion.

Hastelloy C-22 alloy has applications in various fields such as

·        Acetic Acid/Acetic Anhydride

·        Cellophane Manufacturing

·        Complex Acid Mixtures

·        Expansion Bellows

·        Geothermal Wells

·        Incineration Scrubber Systems

·        Pesticide Production

·        Pickling Systems

·        Selective Leaching Systems

·        Sulfonation Systems

·        Weld Overlay-Valves

·        SO2 Cooling Towers

·        Tubular Heat Exchangers

·        Plate Heat Exchangers

·        Phosphoric Acid Production

·        Nuclear Fuel Reprocessing

·        HF Furnace Scrubbers

Hastelloy C-22 alloy is available in various forms such as strip, bar, pipe, plate, covered electrodes, tubing, wire, billet, and sheet. Wrought forms of this alloy are furnished in the solution heat-treated condition. Hastelloy C-22 alloy's performance against crevice corrosion, pitting and stress corrosion cracking is excellent. It also has high resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chloride ions. This alloy has high resistance to environments where reducing and oxidizing conditions are encountered in process streams. It can be used in multi-purpose plants and where upset conditions occur. It has high resistance to various chemical process environments including strong oxidizers such as ferric and cupric chlorides, hot contaminated solutions (Organic and Inorganic), chlorine, acetic anhydride, brine solutions, formic & acetic acids and sea water. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone thus making it appropriate for numerous chemical process applications in the as-welded condition.

Hastelloy C-22 alloy is used in papermill as it passes extensive testing in the actual bleach washer environment for corrosion resistance. It has high resistance for the hydrofluoric acid prescrubber and for the clamshell bellows. It is used in a steel finishing manufacturing line in the form of Sleeved electrogalvanizing finishing rolls. This alloy helps in reducing the defects on the rolls that is essential to manufacture defect-free galvanized steel for the automotive industry. Acid pump strengthened with Hastelloy C-22 alloy is suitable for use in a continuous stainless steel pickling operation. This acid consists of 2 percent hydrofluoric acid, 20 percent hydrochloric acid and 40 gm/liter of iron at 170°F. Hastelloy C-22 alloy is effectively used in severe conditions such as in C-stage bleaching operations in a mill. This alloy is used as a thin-sheet lined for exposure in a utility flue-gas desulfurization plant. It is used as a fan to handle the incineration of radioactive and hazardous wastes due to its durability and corrosion resistance. Hastelloy C-22 alloy filler metal is a cost-effective, reliable and practical solution to corrosion weld problems.
