Kanthal APMT Tubes

Kanthal APMT is an advanced powder metallurgical, dispersion strengthened, ferritic iron-chromium-aluminium alloy (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 carburizing, as well as against deposits of carbon, ash, etc. The combination of excellent oxidation properties and form stability makes the alloy unique.

At SRG we can fabricate Kanthal tubes in different sizes and configurations. We offer the tubes open or closed with sanitary, threaded, or compression mounting. An oxide layer is pre-grown to help protect the tube from gases that normally attack the base metal.
