GH2132
GH2132 alloy is a Fe-25Ni-15Cr-based high-temperature alloy, which is comprehensively strengthened by adding molybdenum, titanium, aluminum, vanadium and trace boron. It has high yield strength, long-lasting and creep strength below 650℃, good processing plasticity and satisfactory welding performance. It is suitable for manufacturing high-temperature load-bearing parts of aircraft engines that work for a long time below 650℃, such as turbine disks, compressor disks, rotor blades and fasteners.
