In Stock APMT Heat Resistant Strip Superior Anti-Oxidation Anti-Carburization High Temperature Alloy Band Custom Slitting Cutting for Continuous Heat Treatment Furnace Components
APMT is an advanced oxide dispersion-strengthened (ODS) FeCrAl high-temperature alloy. Compared with conventional FeCrAl materials, it significantly improves high-temperature performance through the addition of molybdenum and optimized microstructural design. The material contains a uniform distribution of stable yttrium oxide particles, which provide excellent creep resistance and structural stability at elevated temperatures.
APMT can operate continuously in air at temperatures up to approximately 1250°C, while maintaining strong oxidation resistance. A dense and protective aluminum oxide layer forms on its surface, effectively preventing further oxidation and material degradation. Compared with APM, APMT contains molybdenum, which provides higher high-temperature strength and improved resistance to deformation, making it especially suitable for furnace components subjected to mechanical load.
APMT is widely used in industrial heat-treatment furnaces, radiant tubes, furnace support structures, and high-temperature atmospheric equipment. It is a key material that combines high-temperature strength, long service life, and excellent oxidation resistance.
