Incoloy 800H (UNS N08810)
Incoloy 800HT (UNS N08811)

The INCOLOY® 800 series of alloys, invented by the Metal Trading Corporation Group of Companies, is the result of years of monitoring and maintaining the ultimate chemical properties for high-temperature strength and resistance to oxidation, carburization and other types of high-temperature corrosion.® Alloy 800 H is characterized by:

  • Good creep rupture strength at temperature above 600 °C (1,112 °F).
  • Good resistance in oxidizing, nitriding and carburizing conditions.
  • Metallurgical stability in long-term use at high temperatures.

Applications

Alloy 800H and Alloy 800 HT have a wide range of applications in areas of elevated temperatures in furnace construction, in the chemical industry, in environmental protection equipment, in the automotive industry and in power plants. Typical applications include furnace muffles, containers, bins, holders in various heat treatment plants and burner components.

Because of their resistance to carburization and nitriding, the alloys are furthermore used in the areas of

  •  Steam/hydrocarbon reformers
  •  Ethylene pyrolysis
  •  Equipment for acetic anhydride and ketone production
