GH5188 high temperature alloy

GH5188 is a CO-NI-CR based solid solution strengthened deformed high temperature alloy with a service temperature less than 1100℃. The alloy is solid solution strengthened by adding 14% tungsten, which gives the alloy good overall performance; the addition of higher content of chromium and trace lanthanum gives the alloy good high temperature oxidation resistance. The alloy has good cold and hot processing plasticity and welding and other process properties, suitable for the production of 980 ℃ below the requirements of high strength and in 1100 ℃ below the requirements of anti-oxidation of aircraft engine parts.

GH5188 is a solid solution strengthened cobalt based high temperature alloy. The solid solution is reinforced with 14% tungsten to give the alloy excellent high temperature thermal strength. The addition of high chromium and trace. 　　Lanthanum makes the alloy have good high temperature oxidation resistance and satisfactory forming and welding properties, suitable for the manufacture of aircraft engines below 980℃ 　　Parts requiring high strength and oxidation resistance below 1100°C. It can also be used for aerospace engines and space shuttles. It can produce and supply various deformed products, such as thin 　　plate, medium-thick plate, strip, bar, forgings, wire and precision castings. GH5188 corresponding grades. GH5188, GH188, HAYNES ALLOY NO.188, HA188, UNS R30188, KCN22W , ALLOY188, 2.4683 GH5188 heat treatment system. Forged bars, ring-shaped parts: 1180℃±10℃, choose to ensure the mechanical properties of the product qualified rate of cooling. Cold-rolled plates and strips: 1165～1230℃, fast air-cooling. Hot-rolled plate: 1170～1190℃, air-cooling. GH5188 welding. Alloy 188 is easily machined, suitable for both manual and automatic welding, and is welded by electron beam, tungsten gas argon arc welding and resistance welding. Compared with HAYNES 25 alloy, it has excellent strength, oxidation resistance and thermal stability, and good resistance to sulfidation.
