Product Description and Application

GH4090 is a Ni-Cr-Co-based precipitation hardening deformation high temperature alloy, the use of temperature up to 920 degrees. The alloy has high tensile strength and creep resistance at 815 ℃ ~ 870 ℃, good oxidation resistance and corrosion resistance, and high fatigue strength under the repeated alternating action of cold and heat.

GH4090 has good processing and welding performance. It is suitable for making turbine disks, blades, high temperature fasteners, clamps, sealing rings and elastic elements of aviation turbine engines. The main products are hot-rolled bars, cold-drawn bars, cold-rolled plates, strips and cold-drawn materials.

GH4090 has been used in the production of aero-engine high-temperature spring components, high-temperature fasteners, combustion chamber rings and stop pins and other components. Similar brands are also used in the production of aero-engine turbine blades, turbine discs and other parts abroad. GH4090 has good oxidation resistance and corrosion resistance below 1040 ℃, and intergranular oxidation is easy to occur when it is above 1040 ℃.
