Product classification
GH4093
GH4093 is a nickel-chromium-cobalt-based precipitation hardening high-temperature alloy, widely used in aerospace, chemical, and nuclear energy fields due to its excellent performance in high-temperature environments. It has good hot workability, allowing for a deformation amount of 80% without cracking in the temperature range of 1050 to 1150°C. - It has good welding performance, and plates can be connected using argon arc welding. After welding in the solution-treated state, stress relief and aging treatment should be performed. - The average grain size is closely related to the degree of deformation of the forged piece and the final forging temperature. - The cutting performance in the solution-treated state is better than that in the aged state.
