Description:
ALLOY 800 (UNS N08800 / W. Nr. 1.4876)
Common Trade Names: INCOLOY® alloy 800
Alloy 800 is a widely used material for construction of equipment requiring corrosion resistance,
heat resistance, Strength, and stability for service up to 816°C. Alloy 800 offers general corrosion
resistance to many aqueous media and, by virtue of its content of nickel, resists stress corrosion cracking.
At elevated temperatures it offers resistance to oxidation, carburization, and sulfidation along with
rupture and creep strength. For applications requiring greater resistance to stress rupture and creep,
especially at temperatures above 816°C, Alloys 800H and 800HT are used. The chromium in the
alloy imparts both aqueous and heat resistance. Iron provides resistance to internal oxidation.
The nickel content maintains a ductile, austenitic structure. Thus, alloy 800 is readily formed,
welded, and machined
