GH5605
GH5605 is a CO-Cr-Ni based solid solution strengthened deformation high temperature alloy , with a service temperature below 1000 degrees Celsius. Ni-Cr and W are added to the alloy for solid solution strengthening. The alloy has high strength and oxidation resistance. It also has good elastic modulus, wear resistance and welding performance.
The addition of trace rare earth element yttrium improves the hot processing plasticity and cold forming process performance.
