Incoloy 800H/N08810 Nickel Alloy Pipe/Tube

Name: Incoloy 800H/N08810 Nickel Alloy Pipe/Tube
Brand: YUHONG GROUP CO.,LIMITED

Incoloy 800H is a slightly modified version of Incoloy 800 with the 800H grade possessing higher creep and rupture strength. The modification of incoloy alloy 800H pipe is possible because of the closely controlled carbon content and modified heat treatment.

Incoloy Alloy 800H Pipe Highlights

Incoloy 800H(UNS N08810) pipe has a restricted carbon content range of 0.05 to 0.10%, which is in the upper portion of that of Incoloy 800 tube and is annealed at 1149 to 1177℃ (Incoloy 800 is annealed at 983 to 1038℃). These differences impart Incoloy 800H pipe to have higher stress rupture and creep properties than Incoloy 800.
