GH2150 (GH150) Mechanical Properties Tensile strength σb (MPa): ≥950 Conditions yield strength σ0.2 (MPa): 800 Elongation δ5 (%): ≥16.0 section shrinkage ψ (%): ≥20 4. GH2150 (GH150) Key Features: GH2150 (GH150) 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 in solid solution It can form a compound strengthening phase, so commonly used in the form of a solid solution heat treatment and aging process on the substrate. By solution treatment, the GH2150 (GH150) 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.GH2150 (GH150) Application examples: GH2150 (GH150) used to make 700 ~ 750 ℃ ??in aviation, aerospace, gas turbine disc, Blades and other high-temperature components, and general bearing parts other industrial use.
