The Effect Of The Chemical Composition Of GH2132 Alloy

1. GH2132 alloy has high yield strength and enduring, creep strength below 650°C. This is mainly attributed to its complex microstructure, including uniformly distributed diffuse phases and solid solutions. In particular, the precipitation strengthening of the γ’-Ni3(Ti, Al) phase allows the alloy to exhibit excellent mechanical properties at elevated temperatures.
2. The presence of chromium (Cr) confers good corrosion resistance to GH2132 alloy, enabling it to operate stably in high temperature and corrosive environments.
3. GH2132 alloy has good machining plasticity and satisfactory weldability, thanks to its comprehensively strengthened design, including added elements such as molybdenum, titanium, aluminum, vanadium and trace boron.
4. In terms of mechanical properties, GH2132 alloy has a tensile strength of 115-234 MPa, a yield strength of 23 MPa, a ductility of 65%, an HBS grade of 123-321 and an HRC grade of 30
   The HBS grade is 123-321, and the HRC grade is 30.
