description

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.

Features: Incoloy 800H has a restricted carbon content range of 0.05 to 0.10%, which is in the upper portion of that of Incoloy 800, and is annealed at 1149 to 1177℃ (Incoloy 800 is annealed at 983 to 1038℃). These differences impart it to have higher stress rupture and creep properties than Incoloy 800.

Applications: Chemical and petrochemical process piping, high temperature heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam superheating tubing.
