GH5605 high temperature alloy

GH5605 is a Co-Cr-Ni based solid solution reinforced deformed high temperature alloy with a service temperature below 1000°C. The alloy is solid solution strengthened with ω(Cr) 20% and ω(W) 15%. The GH5605 alloy has moderate endurance and creep strength below 815°C, excellent oxidation resistance below 1090°C, and good processability such as machining and welding.

GH5605 is a Co-Ni-Cr based solid solution strengthened deformed high temperature alloy with a service temperature below 1000°C. The alloy is solid solution strengthened with 20% chromium and 15% tungsten. The alloy has moderate persistence and creep strength below 815°C, excellent oxidation resistance below 1090°C, and good process performance in machining and welding. The main products are hot rolled sheets, cold rolled sheets, cold rolled strips, bars, forgings, and steel wire. GH5605 high temperature alloy has been used in the manufacture of high temperature parts such as aero-engine guide vanes, turbine outer rings, outer walls, volutes, and seals. GH5605 high temperature alloy is suitable for jet engines, gas turbines, and marine atmospheric operating environments. It is resistant to oxidation and carbonization at a low temperature of 870°C when working under intermittent conditions*** and up to 1090°C when working continuously under such gas conditions. This alloy is very sensitive to the amount of elemental silicon. Si can promote the formation of C2WLaves phase when the alloy is exposed between 760°C and 925°C, thus reducing the room temperature plasticity of the alloy. Therefore, Si0.4% should be controlled in the alloy. GH605 is a cobalt-based high temperature alloy for 20Cr and 15W solid solution strengthening. The alloy is melted by electric arc furnace or non-vacuum induction furnace and then remelted by adding electroslag, or melted and electroslag remelted by vacuum induction furnace. The alloy works in a jet engine gas turbine environment with moderate persistence and creep strength under intermittent conditions, excellent oxidation resistance up to 1090°C, oxidation and carbonization down to 780°C under intermittent conditions, and up to 1090°C under continuous air conditions. The alloy can also be worked in marine atmosphere
