GH3039
GH3039 is a single-phase austenitic solid solution strengthened alloy with moderate thermal strength and good thermal fatigue properties below 800°C, and good oxidation resistance below 1000°C. The structure is stable after long-term use, and it also has good cold formability and welding performance. Suitable for long-term use of aircraft engine combustion chamber and afterburner components below 850°C. The alloy can be used to produce sheets, rods, wires, tubes and forgings.
