Incoloy 800/800H/800HT(Alloy 800/800H/800HT)  (UNS N08800/UNS N08810/UNS N08811/UNS N08825) are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H/HT and the addition of up to 1.20 percent aluminium and titanium in alloy 800HT. 800 was the first of these alloys and it was slightly modified into 800H. This modification was to control carbon (0.05-0.10%) and grain size to optimize stress rupture properties.

Incoloy 800 offers general corrosion resistance to many aqueous media and, by virtue of its content of nickel, resists stress corrosion cracking.  Incoloy 800H/HT was intended for high temperature structural applications, especially at temperatures above 1500°F (816°C). The nickel content makes the alloys highly resistant to both carborisation and to embrittlement from precipitation of sigma phase.
