GH3039 Alloy

GH3039 is a single-phase austenite-type solid solution strengthening alloy, below 800 ℃ with moderate thermal strength and good thermal fatigue properties, 1000 ℃ below the good oxidation resistance. Long-term use of tissue stability, but also has good cold formability and welding performance. Suitable for long-term use of 850 ℃ below the aero-engine combustion chamber and afterburner parts. The alloy can produce sheet, bar, wire, pipe and forgings.

GH3039 high temperature alloy has the following mechanical properties:

High temperature strength: Maintains high strength in high temperature environments, especially suitable for use in the range of 600–900°C.

Oxidation resistance: Shows excellent oxidation resistance at high temperatures and can be used in oxidizing environments for a long time without significant degradation of mechanical properties.

Creep and rupture resistance: Shows good creep and rupture properties, and maintains stability under high temperature and stress conditions.

Hot working: GH3039 alloy is suitable for various hot working processes such as forging, rolling and extrusion. The hot working temperature range is generally 1080–1150°C.

Cold working: Although GH3039 can be cold worked, its high strength makes cold working challenging and requires advanced equipment and technology.

Welding: GH3039 can be welded using conventional methods such as TIG (tungsten inert gas), MIG (metal inert gas), and resistance welding. Appropriate preheating and post-weld heat treatment are usually required to ensure welding quality.
