Sandvik Kanthal APMT Seamless tube and pipe
Categories: Metal; Superalloy; Iron Base
Material Notes: KANTHAL APMT is an advanced powder metallurgical, dispersion strengthened, ferritic FeCrAlMo alloy which is used at tube temperatures up to 1250°C (2280°F). KANTHAL APMT tubes have good form stability at high temperature. KANTHAL APMT forms an excellent, non-scaling surface oxide, which gives good protection in most furnace environments, i.e. oxidizing, sulphurous and carbonaceous gas, as well as against deposits of carbon, ash, etc. The combination of excellent oxidation properties and form stability makes the alloy unique.

Typical applications for KANTHAL APMT are as radiant tubes in electrically or gas fired furnaces such as continuous annealing and galvanizing furnaces, seal quench furnaces, holding furnaces and dosing furnaces in the aluminium, zinc, lead industries, thermocouple protection tubes, furnace muffles for sintering applications.
