What is the material of high-temperature alloy GH3039?
 

GH3039 is a single-phase austenitic solid solution reinforced alloy with moderate hot strength, good thermal fatigue performance below 800℃, and good oxidation resistance below 1000℃. This alloy has a stable microstructure, is suitable for long-term use, and exhibits good cold formability and weldability.
