GH2132 (GH132) Key Features: GH2132 (GH132) alloy is Fe-25Ni-15Cr base superalloy, adding molybdenum, titanium, aluminum, vanadium and trace boron integrated strengthening. Below 650 ℃ having a high yield strength and durability, creep strength, and has good processing plasticity and satisfactory welding performance. GH2132 (GH132) alloy of chromium and nickel content is relatively low, so the anti-oxidation temperature is only about 800%, but with dispersion strengthening phase forming elements (v, A1, Ti) is relatively high, the solid solution strengthening the matrix may be formed compound phase, so commonly used in the form of a solid solution heat treatment and aging treatment. By solution treatment, the GH2132 (GH132) solid solution strengthening alloy; aging treatment, can strengthen the alloy phase precipitation of fine [VC, Ni3A1, Ni3Ti, Ni3 (A1 Ti?)], Thereby increasing temperature and high temperature strength. Organization after solution and aging treatment of austenite + diffusion compound. 5.GH2132 (GH132) Application examples: GH2132 (GH132) alloy deformation of the product can be produced in various shapes, such as: plate, forgings, plates, rods, wire and annular parts. GH2132 (GH132) suitable for the manufacture of aircraft engines, high-temperature load-bearing parts below 650 ℃ long-term work, such as a turbine disk, annular member, compressor disk, rotor blades, stamping and welding parts and fastener materials.
