Kanthal APM radiant tubes are high-performance heating elements made from Kanthal APM alloy, which is an iron-chromium-aluminium (FeCrAl) alloy. These tubes are designed for use in high-temperature industrial heating applications. Here are some key features:
- High Temperature Resistance: Kanthal APM radiant tubes can withstand temperatures up to 1250°C (2280°F).
- Durability: They offer excellent resistance to carburization, thermal shock, sagging, and distortion.
- Corrosion Resistance: The alloy forms a dense and adherent oxide film that protects against corrosion and atmospheric attack.
- Long Service Life: These tubes have a longer service life compared to other materials like nickel-chromium (NiCr) alloy-based tubes.
- Applications: Commonly used in electrically or gas-fired furnaces, such as continuous galvanizing furnaces, seal quench furnaces, etc.
