High-performance alloy material for industrial engineering and critical application conditions.
1. Introduction to GH5605/605 Materials
GH5605 is a Co-Cr-Ni solid-solution strengthened wrought superalloy applicable for service temperatures below 1000℃. Nickel, chromium and tungsten are added for solid solution strengthening. The alloy features high strength, outstanding oxidation resistance, good elastic modulus, wear resistance and weldability. Trace rare earth yttrium improves hot workability and cold forming performance. Main supply forms: hot rolled bars 10~100mm, forged bars 100mm~350mm, cold rolled thin sheets 0.05mm-4.0mm, wires 4mm~14mm, strips 2mm-10mm, and various custom non-standard forgings.
