Kanthal® furnace tubes, made from FeCrAl and NiCr alloys, withstand temperatures up to 1,250°C. Ideal for radiant, thermocouple protection, and muffle tubes, they offer superior durability and efficiency for industrial heating applications.
Radiant tubes for very high temperatures and severe conditions Tubes made of Kanthal® APM or Kanthal® APMT iron-chromium-aluminium (FeCrAl alloys) are designed to withstand higher temperatures as well as carburizing and sulfidizing atmospheres. Their service life is considerably longer
Radiant tubes for medium high temperatures When furnace conditions are not too demanding, a nickel-chromium (NiCr) radiant tube can prove to be the most economical choice.
Kanthal® APM and APMT FeCrAl alloy furnace tubes provide superior resistance to carburization, thermal shock, and distortion. Ideal for high-temperature industrial applications, they ensure longer service life and reliability.
Radiant tubes for tougher conditions at the burner leg In some furnaces not all parts of a radiant tube is exposed to extreme temperatures. In these cases, an alternative is to use Kanthal® APM or Kanthal® APMT iron-chromium-aluminium (FeCrAl) alloy for the burner leg and a nickel-chromium
Kanthal® Super HT is designed for a longer lifetime of small dimension elements in temperature cycling conditions. The maximum operating temperature is 1830°C (3330°F), and the element is suitable for furnace temperatures between 1500–1750°C (2730–3180°F) approximately.
