Description

Incoloy 800HT has superior corrosion resistance in oxidizing corrosive environments such as nitric acid and nitric acid-sulfuric acid. They perform similarly well in sodium salt and other molten salt environments, and provide stress corrosion crack sensitivity surpassing standard austenitic stainless steels. Alloy 800HT are widely used in chemical plants, heat treatment furnaces and other high-temperature environments.

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.
