Description
1. Introduction to GH5605/605 Materials
GH5605 is a CO-Cr-Ni-based solid solution reinforced deformation high-temperature alloy with a service temperature below 1000 degrees Celsius. NI-Cr and W were added to the alloy for solid solution strengthening. The alloy has high strength and resistance to yang. It also has good elastic modulus, wear resistance and welding performance. The addition of trace amounts of rare earth element yttrium improves the performance of hot processing plasticity and cold forming process. The main products include hot rods 10~100mm, forged rods: 100mm~350mm, cold-tied thin plate 0.05mm-4.0mm, hot rods: 4mm~14mm, with 2mm-10mm, and various non-standard forgings.
