GH90 High-Temperature Alloy GH90 Price GH90

GH90 alloy has the following characteristics:

GH90 is an age-hardened nickel-based wrought superalloy containing a high amount of cobalt and various strengthening elements. This alloy exhibits high tensile strength and creep resistance at 815–870°C, good oxidation and corrosion resistance, high fatigue strength under alternating thermal and mechanical stresses, as well as good formability and weldability. It is used in turbine en

GH90 Process Performance Requirements:

GH90 alloy is prone to internal cracking during forging. Heavy hammering is not allowed, and low-temperature edge chamfering is prohibited. The furnace charging temperature for ingots should not exceed 700°C, with a final heating temperature of 1150°C ± 10°C. The forging start temperature should be no lower than 1060°C, and the finish forging temperature should be no lower than 950°C.

The average grain size of the alloy is closely related to the degree of deformation and the finish forging temperature.

In the solution-treated state, the alloy can undergo inert gas tungsten arc welding and flash welding.

After charging into the furnace, preheat in the low-temperature zone for about 20–30 minutes, then push into the high-temperature zone for heating at 1150–1180°C.

Used in turbine discs, blades, high-temperature fasteners, clamps, seals, and elastic components, etc.
