The chemical composition of UNS N08810（Incoloy800H）
Tech Center 2025-08-01 5
Nickel-iron-chromium alloy, compared with Incoloy 800, has the same matrix composition but significantly higher creep strength. The higher strength stems from the strict control of the contents of C, AI and Ti, along with the combined effect of heat treatment. Used in petrochemical processes, heater and reheater pipeline systems in power plants, industrial circuits, and heat treatment equipment.
Standard product forms: pipes, plates, strips, round bars, flat bars, forgings, wires, and special-shaped materials.
Like Incoloy800 alloy, it is also an austenitic solid solution strengthening alloy with a face-centered cubic lattice structure. Titanium carbide and chromium carbide usually occur in the microstructure.
The density of this alloy is ρ=7.94g/cm³.
