To Be your reliable alloy solution supplier
GH3039
GH3039 is a single phase austenitic solid solution strengthened alloy with medium thermal strength and good thermal fatigue properties below 800 ℃, and good oxidation resistance below 1000 ℃. The structure is stable after long-term use, and it also has good cold formability and weldability. Parts and components of aeroengine combustion chamber and afterburner suitable for long-term use below 850 ℃. GH3039 has good processing plasticity and good deformation performance. Forging heating: 1170 ℃, final forging: 900 ℃; The average grain size is closely related to the deformation degree and final forging temperature of forgings. It can be welded by argon arc welding, spot welding or seam welding. Its welding performance is excellent and the crack tendency of argon arc welding is small. After heat treatment, the oxide scale on the part surface can be removed by sand blowing or acid cleaning.
