Incoloy 800H and 800HT have high temperature strength and resistance to creep and rupture.

Incoloy 800H and 800HT are austenitic, solid solution alloys. Titanium nitrides, titanium carbides, and chromium carbides normally appear in the alloys’ microstructure. The nitrides are stable at all temperatures below the melting point and are therefore unaffected by heat treatment. Chromium carbides precipitate in the alloys at temperatures between 1000 and 2000°F (540 and 1095°C). Consequently, Alloys 800H and 800HT are similar to other austenitic alloys in that they can be rendered susceptible to intergranular corrosion (sensitized) in certain aggressive environments by exposure to temperatures of 1000 to 1400°F (540-760°C). Incoloy 800H and Incoloy 800HT products are produced so as to optimize their high temperature properties. The carbon content in UNS N08810 and UNS N08811 results in high temperature strength and resistance to creep and rupture. Alloy 800H and Alloy 800HT products are solution annealed as a final stage of production so that the carbon is in the condition to make its optimum contribution to high temperature properties. The solution anneal also results in a large grain size which further contributes to strength and resistance to creep and rupture at high temperatures.
