GH3039 superalloy is mainly used in the manufacture of combustion chambers and afterburner parts of aero engines. Afterburner components are a key component in aero engines, whose function is to increase combustion efficiency and thrust in the combustion chamber. These components often require high strength and durability in high-temperature, high-pressure, and high-load environments.
The afterburner is an important part of the aero engine, and its main function is to increase the combustion efficiency and improve the thrust by introducing external air into the combustion chamber. Afterburner components refer to the various components that make up this system, including but not limited to various parts that withstand high pressure, high temperature and high-speed air flow in a high-temperature environment, such as nozzles, guide vanes, etc.
Compared with other superalloys, GH3039 has moderate thermal strength, good resistance to cold and heat fatigue and excellent oxidation resistance. Compared to some nickel-based alloys such as GH3030, GH3039 may exhibit better wear resistance. In addition, the cold forming and welding performance of GH3039 is also one of its advantages.
Thermal Strength:GH3039 exhibits moderate thermal strength below 800 and is suitable for high temperature environments.
Resistance to heat and cold fatigue:It exhibits good resistance to cold and heat fatigue and is able to maintain its strength under cyclic temperature changes.
Antioxidant Properties:Below 1000, it has excellent oxidation resistance and protects parts from high-temperature oxidation.
Cold forming and welding performance:It has good cold forming and welding properties, making it easier to process and assemble during the manufacturing process.
Comply with GB T14992 classification and grade of high-temperature materials for superalloys and intermetallic compounds, as well as other relevant standards such as GB T 15062, GJB 1952A, etc.
The smelting process of GH3039 adopts electric arc furnace, electric arc furnace + electroslag remelting, electric arc furnace + vacuum self-consumable remelting and other methods to ensure that the composition and purity of the alloy meet the standard requirements and ensure the high quality of the material.
