Aerospace
GH1140 is widely used in aerospace applications, including the manufacture of turbine blades, exhaust valves, and other engine components that are subjected to extreme thermal and mechanical stress.
Power Generation
In the power generation sector, GH1140 is used in steam turbines and gas turbines. Its high-temperature resistance and durability are crucial for ensuring the efficient operation of power plants.
Petrochemical and Chemical Processing
GH1140 alloy’s ability to withstand corrosion and oxidation in high-temperature and chemical environments makes it ideal for components such as heat exchangers, reactor parts, and high-performance valves.
Marine Industry
The alloy is also used in the marine industry for engine parts and other components exposed to high temperatures and harsh marine environments.
Automotive
Automotive industries use GH1140 in parts like turbochargers and exhaust systems where high performance at elevated temperatures is critical for ensuring reliability and longevity.
Melting
The process starts with the melting of high-purity raw materials in an electric arc or induction furnace, which ensures the removal of impurities and achieves the desired alloy composition.
Casting
After refining, the molten metal is cast into ingots. These ingots undergo homogenization heat treatment to enhance material uniformity and eliminate segregation.
Forging
The ingots are hot-forged at temperatures exceeding 1100°C. This process refines the microstructure, improving the mechanical properties of the alloy.
Hot Rolling
The forged ingots are then hot-rolled to achieve the desired dimensions. Hot rolling also enhances the alloy's directional properties, making it suitable for high-stress applications.
Annealing
The rolled bars are annealed at temperatures between 900°C and 950°C to relieve internal stresses, ensuring improved ductility and better performance during subsequent machining.
Finishing
The final step involves cutting the rods to the required length, followed by any necessary surface treatments such as polishing, grinding, or coating to enhance performance and protect against environmental degradation.
