5. Typical Application Environment
The Hastelloy-C22 alloy has been widely used in chemical and petrochemical fields, For example，It can used in equipment components and catalytic systems which contact with chlorinated organic compounds.This material is especially suitable for use in high temperature, mixed inorganic acid and organic acids (such as formic acid and acetic acid) and seawater corrosive environment.
