Alloy 800H Applications
Alloy 800H and Alloy 800 HP 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

Welding Alloy 800
For welding, Alloy 800 H and 800 HP should be in the annealed condition and be free from scale, grease and
markings.Alloy 800 H and 800 HP can be welded using the following procedures: GTAW (TIG), GTAW (TIG)
hot wire, plasma, SMAW (MMA), GMAW (MIG/MAG) and submerged arc welding.
Filler metal
The following filler materials are recommended:
Welding rods, welding wire and wire electrodes |
