Description
Incoloy 800 is a nickel-iron-chromium alloy known for its excellent high temperature resistance and oxidation resistance, and is widely used in various harsh environments. The chemical composition of the alloy includes about 30-35% nickel, 19-23% chromium and a large amount of iron as a balance element, in addition to small amounts of carbon, aluminum and titanium. Incoloy 800 is designed to provide good oxidation resistance and carburization resistance while maintaining structural stability in high temperature environments.
- Incoloy 800(UNS N08800): base grade, fine grain, good for anti‑corrosion use
- Incoloy 800H(UNS N08810): higher carbon, coarse grain, good high‑temperature creep performance
- Incoloy 800HT(UNS N08811): controlled Al+Ti, better creep‑rupture strength than 800H
Compared with other similar alloys, Incoloy 800 has a lower carbon content (usually below 0.10%), which helps reduce the risk of intergranular corrosion during long-term use at high temperatures.
