Incoloy 800H has a restricted carbon content range of 0.05 to 0.10%, which is in the upper portion of that of Incoloy 800, and is annealed at 1149 to 1177℃ (Incoloy 800 is annealed at 983 to 1038℃). These differences impart it to have higher stress rupture and creep properties than Incoloy 800.

Incoloy 800H (UNS N08810, DIN W. Nr. 1.4958) is a nickel-based alloys grade. Incoloy 800H has a restricted carbon content range of 0.05 to 0.10%, which is in the upper portion of that of Incoloy 800, and is annealed at 1149 to 1177℃ (Incoloy 800 is annealed at 983 to 1038℃). These differences impart it to have higher stress rupture and creep properties than Incoloy 800.
