About Incoloy® 800HT

Incoloy 800ht is a modified variant of alloy 800 among the nickel-iron-chromium alloy family. Alloy 800ht will not be susceptible to embrittlement even after long exporsures to service temperature in rang eof 1200-1600°F. Incoloy 800ht also exhibits excellent cold forming characteristics. Addition of aluminum and titanim to this alloy ensures optimum high temperature properties with high resistance to both chloride stress corrosion cracking and embrittlement from precipitation of sigma phase. Further alloy 800ht has higher creep and rupture properties than alloy 800 and 800h owing to its stringent carbon restriction.
