Sandvik Kanthal AMPT Construction materials
Categories: Metal; Ferrous Metal; Alloy Steel
Material Notes: Kanthal APMT is an advanced powder metallurgical, dispersion strengthened, ferritic Iron chromium aluminum alloy (FeCrAlMo alloy) recommended for continuous use up to 1250°C (2280°F) in oxidizing and reducing environments. Kanthal APMT has high creep strength and excellent form stability up to 1300°C. Kanthal APMT forms a protective and nonscaling Al O surface oxide when exposed to high temperature, which gives good protection in most furnace and combustion environments, i.e. oxidizing, sulphidizing and carburizing, as well as against attacks from deposits of coke, ash, etc. The combination of excellent oxidation properties and form stability makes the alloy unique. The superior resistance of Kanthal APMT to oxidation and carburization makes it very suitable for high temperature construction applications in various atmospheres.

Applications:

  • Radiation tubes for electrical and gas heated furnaces
  • Retorts and muffles for heat treatment and high-temperature sintering of powder metallurgical components
  • Shielding tubes
  • Burner components, nozzles and flame detectors
  • Load carriers, furnace furniture and load carrying trays
  • Radiant cracker tubes in ethylene furnaces
  • Uncooled components in coal, gas, and biofuel fired power plants
  • Thermocouple protection tubes in power plants and high temperature petrochemical processes
