Incoloy 800HT
Alloy 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.
