GH5605 Cobalt-based superalloy GH605

 

GH5605 (GH605) Cobalt-based superalloy overview

GH605 is a 20Cr and 15W solid solution strengthened cobalt-based superalloy. It has moderate durability and creep strength below 815 ℃, excellent oxidation resistance below 1090 ℃, and satisfactory forming, welding and other process performance. It is suitable for manufacturing hot-end high-temperature parts such as aero-engine combustion chamber and guide vane, which require medium strength and excellent high-temperature oxidation resistance. It can also be used on space engines and space shuttles. It can produce and supply various deformed products, such as thin plate, medium plate, strip, bar, forging, wire and precision casting.
