Hastelloy C-22 Corrosion Resistance

Hastelloy C22 alloy is suitable for use in various chemical process industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion erosion, and the tungsten element further improves its corrosion resistance. Hastelloy C22 is one of the only materials that is resistant to corrosion by wet chlorine, hypochlorite and chlorine dioxide solutions. The alloy has significant corrosion resistance to high concentrations of chloride salt solutions (such as ferric chloride and copper chloride).

Hastelloy C-22 Application Scope Application fields include: Hastelloy C22 alloy has been 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 C-22 Other areas of application: Acetic acid/acetic anhydride, acid leaching, cellophane manufacturing, chlorination systems, complex mixed acids, rollers for galvanizing tanks, expansion bellows, flue gas cleaner systems, geothermal wells, hydrogen fluoride furnace cleaning Incineration 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, cladding valve
