ASTM B407 UNS N08810 Incoloy 800H Pipe High Temperature Service Alloy

UNS N08810 is a nickel-iron-chromium alloy specifically designed for high-temperature service requiring good creep and rupture strength above 600C (1112F). 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
