Inconelx-750/UNS NO7750/GH4145
Inconel High strength, good relaxation resistance below 540℃, and good formability and welding performance. The alloy is mainly used to manufacture relaxation-resistant flat springs and coil springs for aircraft engines that operate below 800°C and require high strength. It can also be used to manufacture turbine blades and other parts of steam turbines.
