UNS N08810 is a nickel-iron-chromium alloy specifically designed for high-temperature service requiring good creep and rupture strength above 600°C (1112°F). It is a controlled chemistry version of UNS N08800 (Alloy 800), with tighter limits on carbon (0.05-0.10%) and a coarse grain size requirement (ASTM 5 or coarser) to optimize high-temperature properties.
The alloy maintains an austenitic structure and offers excellent oxidation and carburization resistance, as well as good corrosion resistance in high-temperature environments. UNS N08810 is particularly valued for its superior creep-rupture strength compared to standard 800, making it the preferred choice for petrochemical furnaces, heat treating equipment, and power generation components operating in the 600-900°C range.
