Audited Supplier The gh2132 alloy is a Fe-25Ni-15Cr-based superalloy, which is comprehensively strengthened by adding molybdenum, titanium, aluminum, vanadium and a trace amount of 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.
The alloy can produce various shape deformed products, such as: discs, forgings, plates, rods, wires and rings.
Similar material grade: ZbNCT25 (France)
