Alloy grade comparison table


GH4169 alloy is a nickel-based superalloy strengthened by the precipitation of body-centered tetragonal γ" and face-centered cubic γ′ phases. It exhibits excellent comprehensive performance in the temperature range of -253 to 700°C, with the highest yield strength among deformed high-temperature alloys below 650°C. It also has good fatigue resistance, radiation resistance, oxidation resistance, and corrosion resistance, as well as good machinability, weldability, and long-term microstructural stability. This allows for the manufacturing of complex-shaped components, leading to extensive applications in aerospace, nuclear energy, and the petroleum industry within the specified temperature range.
