Incoloy alloy 800 is nickel-iron-chromium alloys with good strength and
excellent resistance to oxidation and carburization in high-temperature
exposure. Incoloy alloy 800 was the first of these alloys and it was
slightly modified into Incoloy 800H. This modification was to control
carbon (.05-.10%) and grain size to optimize stress rupture properties.
The nickel content makes the alloys highly resistant to both chloride
stress-corrosion cracking and to embrittlement from precipitation of
sigma phase. The general corrosion resistance is excellent. In the
solution annealed condition.
Incoloy 800 is primarily used in applications with temperatures up to
1100° F. The chemical balance allows the nickel steel alloy to exhibit
excellent resistance to carburization, oxidation and nitriding
atmospheres.
