Incoloy Alloy 800 is a widely used structural material for equipment that must have high strength and resist oxidation, carburizing and other harmful effects of high temperature exposure (for high temperature applications requiring optimal creep and fracture properties, use Incoloy Alloy 800H and 800HT).
The major differences between alloys 800, 800H and 800HT are mechanical properties. The differences stem from the restricted compositions of alloys 800H and 800HT and the high-temperature anneals used for these alloys. In general, alloy 800 has higher mechanical properties at room temperature and during short-time exposure to elevated temperatures, whereas alloys 800H and 800HT have superior creep and rupture strength during extended high temperature exposure.
