Incoloy 800H has excellent corrosion resistance in
the water media at extremely high temperature of 500℃.
Its higher nickel content made it have good stress corrosion resistance
cracking properties in the water corrosion condition. High chromium content
made it better resistance to pitting and crevice corrosion cracking. This alloy
can resist nitric acid and organic acid, but it is not so fine in the sulfuric
acid and hydrochloric acid.
