(1) Category A is a regular supply condition. (2) Category B is limited to the supply conditions of bars with a diameter of 32 mm for special conditions for aerospace. (3) When the initial test of durable performance is unqualified, the test shall be repeated according to the indicators in parentheses.

GH302 Alloy properties：

After fine crystallization process + direct aging treatment, HuaNickel GH2130 alloy can be used to produce high yield, high fatigue performance discs and long-life rotor blades at 500°C~700°C. When the service temperature is greater than 700°C, the durability and creep limits of the alloy begin to decrease; After long-term aging, the alloy has Laves phase precipitation, which reduces the impact toughness at room temperature. When the alloy is used at 800°C, the surface can be Al-loaded to improve the oxidation and corrosion resistance.

GH2130 Uses of alloys：

GH2130 alloy has been used in the manufacture of aero engine working blades, marine turbine supercharged turbines, spacecraft fasteners, etc.

GH2130 Process performance：

Surface treatment process: In order to eliminate the residual stress on the surface of the finished parts, argon protection can be used, and the aging can be supplemented by 1000°C±10°C ×(10~15) min/AC+800°C± 10°C×4h/AC. When the alloy is used at 800°C, the surface can be infiltrated to improve the oxidation and corrosion resistance.
