The chemical composition for Incoloy 800HT (UNS N08811) are more restrictive. difference between 800HT and 800H is that the chemical limit of Incoloy 800HT will never cross the limits of Incoloy 800H.The carbon content for Incoloy alloy 800HT is 0.06 – 0.10%. Additionally, the Al plus Ti content of Incoloy alloy 800HT is 0.85 – 1.20%. it is Also called as Nickel Alloy 800HT. Incoloy 800HT applications include In power generation, petrochemical processing reformer tubing ,superheater and reheater tubing, bellows and flare tips in refinery service, fixtures and muffles jigs, Heat treatment retorts have also used this material to best effect.
Heubach international created by the Special Metals Corporation.Incoloy alloy 800HT (UNS N08811) The maximum allowable stresses are contained in ASME Code Case 1987 – latest revision.Incoloy alloy 800HT (UNS N08811) has higher maximum allowable design stresses than UNS N08810. thats why other materials manufactured to UNS N08810 (alloy 800H) cannot be certified as UNS N08811 until they meet the additional requirements for this designation.
