Features: Incoloy 800HT ensures higher stress rupture and creep properties compared to Incoloy 800H as a result of restricting the carbon content further in the range of 0.06 to 0.10% (Incoloy 800H is 0.05 to 0.10%), and the aluminum plus titanium content at 0.85 to 1.20% (Incoloy 800H is 0.30 to 1.20%).
Applications: Chemical and petrochemical process piping, high temperature heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam superheating tubing.
