Incoloy 800, 800H, and 800HT are nickel–iron–chromium alloys with carefully controlled carbon and aluminum contents. This composition delivers excellent resistance to oxidation and high-temperature corrosion. The 800H and 800HT grades offer higher carbon content for improved creep and rupture strength at elevated temperatures. Mechanically, these alloys provide good tensile strength, high ductility, and excellent toughness. They maintain dimensional stability and mechanical integrity under prolonged heat and stress.
