Features:
UNS Number N08800
Incoloy 800 has a great 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. As many applications require the higher stress rupture and creep properties, Incoloy 800H and 800HT are recommended when the temperatures is above 816℃. Incoloy 800 is readily formed, welded and machined.
Applications:
Incoloy 800 is applied in Chemical and petrochemical process piping, heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam-generator tubing.
