Inconel 800/800H, IRON-Nickel-Chromium Alloy, Alloy 800/800H

UNS N08800/N08810, EN 1.4876

Inconel 800/800H is an austenitic iron-nickel-chromium alloy. Having low nickel content compared to other nickel alloys, still has resistant heat and corrosion. It has good mechanical properties at a low temperature up to 800 Degree. It has ability to resist against oxidation, carburization and nitriding conditions and good workability.

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
