GH132 alloy is Fe-25Ni-15Cr-based superalloy, which is comprehensively strengthened by adding molybdenum, titanium, aluminum, vanadium and trace boron. It has high yield strength and lasting and creep strength below 650ºC, and has good processing plasticity and satisfactory welding performance. It is suitable for the manufacture of high-temperature load-bearing components of aero-engines that work for a long time below 650 °C, such as turbine disks, compressor disks, rotor blades and fasteners.
