TONG CHUANG'S Incoloy 800H(UNS N08810) 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.
