GH5188 is a Co-Ni-Cr-based solid solution strengthened deformed high-temperature alloy with a service temperature of less than 1100°C. 14% w (W) tungsten is added to GH5188 for solid solution strengthening, so that the alloy has good comprehensive properties; a higher content of chromium and trace amounts are added to give the alloy good high-temperature oxidation resistance. GH5188 has good cold and hot processing plasticity and welding process properties, and is suitable for making aerospace engine parts that require high strength below 980°C and oxidation resistance below 1100°C. The main products include cold-rolled sheets, hot-rolled plates, bars, forgings and wire rods.

GH5188 has been used to make high-temperature components such as aeroengine combustion chamber flame tubes and guide vanes, and is in good batch production and use. Similar alloys are also widely used in high-temperature components of gas turbines and missiles abroad, such as combustion chambers, tail nozzles, and heat exchangers in the nuclear energy industry. In the manufacturing process of GH5188 plate processing parts, any process (such as heat treatment, welding, etc.) should prevent carburization and copper contamination to avoid damaging the mechanical properties and corrosion resistance of the alloy. The corrosion resistance of alloy plates is better than that of GH3536 alloy.
