Product description

GH4090 High-temperature Alloys

High-temperature Alloys can also be called Superalloy Material, today JIADE Steel will bring you together with this GH4090 High-temperature Alloys products.

GH90 is Ni-Cr-Co based precipitation hardening deformation Superalloy Material, the use of temperature up to 920 ℃ ℃ Steel alloy in 815 ℃ ~ 870 ℃ has a high tensile strength and creep resistance, good oxidation and corrosion resistance, in the role of cold and hot repeatedly alternating with high fatigue strength. Because the alloy has good processing and welding properties, it has many applications in aerospace, such as making aero-turbine engine turbine disks, blades, high-temperature fasteners, clamps, seals and elastic components.

Our company can now provide Special Steel Material, which can be customized according to the delivery requirements, such as hot rolled bars, cold drawn bars, cold rolled plates, strips and cold drawn wires, etc. GH4090 high temperature alloy has been used to make aero-engine high-temperature spring originals, high-temperature fasteners, combustion chamber clamps and stop pins and other parts.

GH90 alloy steel has good oxidation resistance and corrosion resistance below 1040℃, but is prone to intergranular oxidation above 1040℃.
