GH4145 alloy is a nickel-based superalloy mainly composed of GH4145 [Ni3(Al, Ti, Nb)]. At temperatures below 980, the alloy has good corrosion and oxidation resistance, which allows it to maintain stable performance in high-temperature environments. At the same time, at temperatures below 800, GH4145 alloy has high strength and can withstand large loads. In addition, at temperatures below 540, the alloy has a strong resistance to relaxation, which means that it can maintain good elasticity during long-term use and is not prone to deformation or relaxation. GH4145 is a similar grade
The formability and welding properties of GH4145 alloy are also very good, which makes it have high machinability and weldability in the manufacturing process. This alloy is mainly used in the manufacture of aircraft engines that work below 800 and require high-strength relaxation plane springs and compression springs. These springs play an important role in aircraft engines and require high strength and corrosion resistance. GH4145 chemical composition
In addition to making springs, GH4145 alloy can also be used to make turbine blades and other components. These components operate at high temperatures, pressures, and speeds, and require excellent corrosion and oxidation resistance. Varieties include plates, belts, bars, forgings, rings, silk and pipes. These different forms of products can meet the needs of different fields. 
GH145 (GH4145) heat treatment system requires different heat treatment processes for different materials and parts. For example, for plates, strips and tubes, a solution heat treatment system is usually used, i.e. heat treatment is carried out at a temperature of 980 15 and then air cooled. For bars, forgings and rings, different heat treatment processes such as annealing, annealing before weldment welding, stress annealing of weldments and stress annealing can be used. 
GH145 (GH4145) varieties and specifications and ** status can provide various specifications of bars, forgings, rings, hot-rolled plates, cold-rolled plates, strips, pipes and wires according to different needs. For sheet and strip, usually after hot or cold rolling, annealing or solution, pickling and polishing**. For bars, forgings and rings, they can be forged or hot-rolled**It can also be solved after forging;After solution, the bar can be polished or polished**. When the order is requested, the cold pull state can be in place. Pipes are solution treated and the oxide layer is removed**. The wire can be in a solid solution state**;For nominal diameters or thicknesses in 6Wire below 35mm can be 50% to 65% cold drawn deformation after solid solution**;The diameter or side length is greater than 635mm nominal filament, after solid solution, with a cold drawing deformation of not less than 30%**. For diameters or side lengths up to 0The nominal wire of 65mm shall be deformed by cold drawing and not less than 15% after solid solution. 
GH145 (GH4145) smelting and casting process alloy adopts different smelting and casting processes such as electric arc furnace plus vacuum self-consumable remelting, vacuum induction plus electroslag, vacuum self-consumable remelting or vacuum induction plus vacuum self-consumption remelting. These processes ensure the uniformity of the composition and microstructure of the alloy, thereby improving its performance and service life. GH145 (GH4145) Application Overview and Special Requirements This alloy is mainly used to manufacture important components in high-temperature, high-pressure and high-speed environments such as aircraft engines. In the process of use, it needs to be selected and used according to specific requirements to ensure its performance and service life.
