(1) Excellent resistance to various corrosive media under oxidation and reduction conditions;It is one of the few materials that can resist the corrosion of moist chlorine gas, hypochlorite and chlorine dioxide solution, and has[SCALE STEEL] significant corrosion resistance to high concentration of salt chloride solution (such as ferric chloride and copper chloride).
(2) It can also resist a variety of corrosive [SCALE STEEL]environments at a high temperature of up to 677℃.
(3)Good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.
(4) Excellent welding performance.
Hastelloy C-22 alloy has been widely used in chemical and petrochemical fields, such as the application in the contact with chloride-containing organic components and catalytic systems.This material is especially suitable for high temperature, mixed with impurities of inorganic acids and organic acids (such as formic acid and acetic acid), sea water corrosion environment.
