The 0Cr27Al7Mo2 FeCrAl rod is a premium high-temperature alloy engineered for industrial furnaces and heater systems operating under extreme conditions. This ferritic alloy is composed primarily of iron (Fe), 27% chromium (Cr), 7% aluminum (Al), and 2% molybdenum (Mo). The combination of chromium and aluminum ensures excellent oxidation resistance, while molybdenum enhances high-temperature mechanical strength and creep resistance, making this alloy ideal for demanding applications.
DLX Alloy produces these rods using vacuum induction melting followed by precision rolling and heat treatment, ensuring a uniform microstructure, low impurity levels, and consistent electrical resistivity. The dense alumina (Al₂O₃) oxide layer that forms on the surface during high-temperature exposure protects the material from oxidation, extending its operational life in furnace and heater systems.
