High temperature alloy GH3039 Description

High temperature alloy GH3039 is a single-phase austenitic solid solution strengthened alloy. It has moderate thermal strength and good thermal fatigue performance below 800°C, good oxidation resistance below 1000°C, stable structure for long-term use, and Has good cold formability and welding performance. Suitable for long-term use below 850℃.

High temperature alloy GH3039 specifications

The intermediate solution heat treatment temperature of the parts is 1050℃, air cooling. The final heat treatment temperature of the parts in the combustion chamber is 1080 ℃. For parts with higher durability requirements for air cooling, the solution temperature can be increased to 1170 ℃. The holding time of the parts during solution heat treatment can be selected according to the thickness of 2-20min. It is recommended after the parts are heat treated After heat treatment, the surface oxide scale of the parts can be removed by sand blowing or pickling.
