GH3039 is a single-phase austenitic solid solution strengthened alloy with moderate thermal strength and good thermal fatigue performance 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 aero engine combustion chamber and afterburner parts for long-term use below 850°C. The alloy can produce plates, bars, wires, pipes and forgings.
