1. Introduction to GH2132 Materials
GH2132 alloy is a Fe-25Ni-15Cr-based high-temperature alloy, and is strengthened with molybdenum, titanium, aluminum, vanadium and trace boron. Below 650°C, it has high yield strength, long-lasting, creep strength, and has good processing plasticity and satisfactory welding properties. Suitable for manufacturing high-temperature bearing components for aircraft engines that work under 650°C for a long time, such as turbine discs, compressor discs, rotor blades and fasteners.
