GH5605(GH605) cobalt-based deformed superalloy

GH605 is a 20Cr and 15W solid solution strengthened cobalt-based high-temperature alloy. It has medium lasting and creep strength below 815ºC, excellent oxidation resistance below 1090ºC, and satisfactory forming and welding process performance. It is suitable for the manufacture of aero-engine combustion chambers and guide vanes that require medium strength and excellent high-temperature oxidation resistance. It can also be used on space engines and space shuttles. Can produce and supply a variety of deformed products, such as thin plates, medium plates, strips, bars, forgings, wires and precision castings.
