Kanthal® APM and Kanthal APMT FeCrAl alloys

Kanthal® APM and Kanthal APMT FeCrAl alloys

Kanthal® APM and Kanthal® APMT iron-chromium-aluminium (FeCrAl) alloys can be used at tube temperatures up to 1250°C (2282°F). They offer several advantages compared to other tube materials such as alumina, silicon carbide and nickel-chromium (NiCr) alloys.

User benefits include superior resistance to, for example, carburization, thermal shock, sagging and distortion. This is due to the materials’ excellent mechanical properties* and their capability of forming a dense and adherent oxide film that protects against corrosion and atmospheric attack.

The service life of Kanthal® APM and Kanthal® APMT furnace tubes is often many times longer than that of nickel-chromium (NiCr) alloy-based tubes

Main characteristics of Kanthal APM and Kanthal APMT FeCrAl alloys

  • Excellent form stability
  • Excellent corrosion resistance in most atmospheres
  • High thermal conductivity
  • No scaling and impurities
  • Longer tube life

Radiant tubes in Kanthal® APM and Kanthal® APMT are available from stock in many sizes. View stock standard sizes and tolerances

* Kanthal APMT offers higher hot strength than Kanthal APM which makes the grade even more resistant to sagging.
