| KANTHAL APM is an advanced powder metallurgical, dispersion strengthened, ferritic FeCrAl alloy which is used at tube temperatures up to 1250°C (2280°F). KANTHAL APM tubes have good form stability at high temperature. KANTHAL APM 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 formstability makes the alloy unique. Typical applications for KANTHAL APM are as radiant tubes in electrically or gas fired furnaces such as continuous galvanizing furnaces, seal quench furnaces, holding furnaces and dosing furnaces in the aluminium, zinc, lead industries, thermocouple protection tubes, furnace muffles for sintering applications.
