Description
INCOLOY Alloy 800HT
INCOLOY® alloy 800HT® is a controlled composition derivative of INCOLOY® alloy 800H (UNS N08810) and is used for the same creep resistant applications, however the combined effects of mechanical and thermal processing of the alloy permit higher design stresses to be incorporated than are permitted for the conventional alloy.
Both materials remain available, subject to commercial considerations, and certain specifications which restrict the service temperature of some grades of INCOLOY® alloy 800H.
Applications have extended from petrochemical processing reformer tubing, to bellows and flare tips in refinery service. In power generation, superheater and reheater tubing has also employed the material. Heat treatment retorts, muffles jigs and fixtures have also used this material to great effect.
