1. Introduction to GH2132 Materials
GH2132 is an Fe-25Ni-15Cr base superalloy strengthened by molybdenum, titanium, aluminum, vanadium and trace boron. It features high yield strength, rupture strength and creep strength below 650℃, excellent hot/cold workability and satisfactory weldability. It is widely used for long-term high-temperature load-bearing aero-engine components working under 650℃, such as turbine disks, compressor disks, rotor blades and fasteners.
