Hastelloy C-22

Hastelloy C22 (N06022) is a nickel-based high-temperature alloy composed of nickel, molybdenum, cobalt, tungsten and other elements, with a nickel content of approximately 60%. It is a versatile nickel-chromium-molybdenum-tungsten alloy that has better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C-276, C4 alloy and 625 alloy. Hastelloy C22 alloy has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. It has excellent antioxidant capabilities in aqueous media including wet chlorine, nitric acid or a mixture of oxidizing acids containing chloride ions.

APPLCATION:

Hastelloy C22 alloy is widely used in the chemical and petrochemical fields, such as in components and catalytic systems that come into contact with chloride-containing organic matter. This material is especially suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosion environments. Hastelloy C22 (N06022) Other application areas of Hastelloy: acetic acid/acetic anhydride, acid leaching, cellophane manufacturing, chlorination systems, complex mixed acids, electro galvanizing tank rollers, expansion bellows, flue gas cleaner systems, geothermal wells , hydrogen fluoride furnace cleaner, combustion cleaner system, nuclear fuel regeneration, pesticide production, phosphoric acid production, pickling system, plate heat exchanger, selective filtration system, sulfur dioxide cooling tower, sulfonation system, tubular heat exchanger, Hardfacing valves.
