GH2132 alloy is 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 and lasting and creep strength below 650ºC, and has good processing plasticity and satisfactory welding performance. It is suitable for manufacturing high-temperature bearing components of aero-engines, such as turbine disks, compressor disks, rotor blades and fasteners, which work for a long time below 650ºC.
