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 strong resistance to stress-corrosion cracking in demanding service conditions. Alloy 800HT is widely used in chemical plants, heat treatment furnaces , and other high-temperature environments.
