Gh5605 gh5605 is a co-ni-cr based solid solution strengthened deformation superalloy with a temperature below 1000 °C. Solid solution strengthening is carried out by adding 20% chromium and 15% tungsten to the alloy.
The alloy has moderate long-term and creep strength below 815 °C, excellent oxidation resistance below 1090 °C, and good processing and welding performance.
The main products are hot rolled sheet, cold rolled sheet, cold rolled strip, bar, forgings and wire. Alloys have been used to manufacture high temperature components such as aerospace engine guide vanes, turbine outer rings, outer walls, swirlers and seals. The alloy is suitable for use in jet engines, gas turbines and marine atmospheres.
The minimum temperature for oxidation and carbonization when operating under intermittent conditions is 870 ° C. Under continuous operating conditions, it can withstand temperatures up to 1090 ° C.
The alloy is sensitive to the silicon content. Silicon promotes the formation of the c2w-type laves phase when exposed between 760 °C and 925 °C, which results in a decrease in the room temperature ductility of the alloy.
Therefore, the alloy should be controlled by si<0.4%.
