In22 alloy is a completely austenitic high-grade corrosion-resistant alloy. In addition to good resistance to general corrosion, stress corrosion cracking, crevice corrosion, pitting corrosion and grain boundary erosion, this alloy also has the ability to resist water corrosion and high temperature corrosion.

In22 application field

• In the marine field

•In the waste treatment industry

•In pulp and paper processing

•In chemical/petrochemical processing

• In pollution control (flue gas desulfurization)

•Used to protect water walls, boiler tubes and other components in coal-fired power generation boilers.
