Incoloy 800 has good rupture and creep strength and excellent resistance to oxidation, carburization and sulfidation at temperatures up to 816℃. It also resists general corrosion by many aqueous media. For applications requiring higher stress rupture and creep properties, especially at temperatures above 816℃, Incoloy 800H and 800HT are recommended. Incoloy 800 is readily formed, welded and machined.

Incoloy 800 (UNS N08800, DIN W. Nr. 1.4876) is a nickel-based alloys grade. Incoloy 800 has good rupture and creep strength and excellent resistance to oxidation, carburization and sulfidation at temperatures up to 816℃. It also resists general corrosion by many aqueous media. For applications requiring higher stress rupture and creep properties, especially at temperatures above 816℃, Incoloy 800H and 800HT are recommended. Incoloy 800 is readily formed, welded and machined.
