Request a Quote

Incoloy 800HT is a fully austenitic, low-carbon nickel-iron-chromium with cobalt content strictly controlled below 0.01%. It offers resistance to a wide range of corrosive media, with high nickel content providing excellent resistance to stress corrosion cracking in aqueous environments. Its high chromium content enhances resistance to pitting and crevice corrosion cracking, making it ideal for high-temperature and corrosive applications.
