GH4202 is a nickel-chromium-based precipitation-strengthened deformed superalloy with an operating temperature range of -253 to 800. 4% (Al+Ti) is added to the alloy to form the aging strengthening phase, 9% (W+Mo) is added for solution strengthening, and a small amount of boron and cerium is added to strengthen and purify the grain boundaries. The alloy has good comprehensive mechanical properties and stable structure. It has high resistance to corrosion and oxidation, as well as excellent resistance to oxygen-rich corrosion. It also has excellent weldability and is a typical multi-purpose superalloy material. The main products are bars, forgings, plates, tubes and wires.
The alloy has been used in the manufacture of dozens of components such as turbine rotors, fairings, turbine spherical shells, bellows and gas pipelines for new high-thrust liquid rocket engines, and has been well applied.
Application Overview & Properties: GH4202 alloy can also be used in a wide range of applications in the aerospace, nuclear, petroleum and chemical industries.
Aerospace: It is widely used in the manufacture of high-temperature components such as engine turbine blades, combustion chambers, and gas turbines, which can withstand extremely high temperatures and pressures to ensure the proper operation of the engine.
Energy: GH4202 superalloy is widely used in high-temperature environments such as gas turbines, nuclear power plants and petrochemical equipment. It can withstand high temperatures and corrosive gases, ensuring safe operation and long service life of the equipment.
Chemistry: GH4202 superalloy is widely used in the manufacture of high-temperature equipment such as reactors, heat exchangers and catalysts. It can withstand high temperatures and corrosive media to ensure the stable operation and efficient production of the equipment.
These industries require heat-resistant bearing parts and welded parts with high corrosion and oxidation resistance. The alloy needs to be welded in a solution state, and heat treatment is required after welding to eliminate residual stresses. There is no precipitation of harmful phases after long-term aging at high temperature.
The application advantage of GH4202 superalloy forgings lies not only in its excellent corrosion resistance, but also in its high-temperature strength, heat resistance and oxidation resistance. The alloy forging can operate for a long time in harsh environments such as high temperature, high pressure and corrosion to ensure the safe and stable operation of the equipment.
In conclusion, GH4202 superalloy is an important high-temperature material with a wide range of application prospects and great economic value.
