Product Description

Alloy GH4169 is Fe-Ni-Cr-base wrought superalloy, it has good welding performance, oxidation resistance,good Processability, especially has excellent   integrated   mechanical   properties.
The superalloy is widely used in the   proper   temperature   range between - 253 ~650ºC. The transient temperature can be reached to 800ºC. 
The superalloy GH4169 have many specification, such as forging rod, hot rolling rod, cold drawn bar, strap, belt, pipe.Typical   parts   made   by   this material are rotor, fastener, elastic   component , and damping element. The parts made by superalloy GH4169 are widely used in various   industries, such as aerospace, nuclear industry, auto industry(new energy),electronic engineering.
