GH4090 high temperature alloy rods are high-performance materials made from a unique combination of cobalt, chromium, nickel, and other alloying elements, designed for extreme high-temperature and high-stress environments. With outstanding resistance to oxidation, corrosion, and fatigue, GH4090 rods are widely used in aerospace applications, particularly in aircraft engine rotor blades, where performance under intense thermal and mechanical stress is critical.
This high-temperature alloy is commonly referred to as a "superalloy" due to its exceptional strength and stability at temperatures exceeding 600°C. GH4090 is known for its ability to retain mechanical properties under extreme conditions, making it an essential material for the most demanding applications in aviation, aerospace, petroleum, and chemical industries.
High-Temperature Strength
GH4090 alloy rods maintain high strength and integrity at temperatures over 600°C, making them ideal for aerospace components like rotor blades in aircraft engines that operate under extreme heat and stress.
Excellent Oxidation and Corrosion Resistance
The high chromium and nickel content in GH4090 provides superior resistance to oxidation and corrosion, even in the most aggressive environments. This ensures longevity and reliability in parts exposed to high heat and chemical environments.
Outstanding Fatigue and Fracture Toughness
GH4090 rods exhibit excellent fatigue performance and fracture toughness, critical for components such as rotor blades, which are subjected to repetitive thermal and mechanical stresses during operation.
Good Fabrication and Machining
GH4090 rods are easy to forge, machine, and weld using standard techniques, allowing for versatile applications and the creation of complex shapes and components required in the aerospace industry.
Thermal Stability
GH4090 offers superior thermal stability, ensuring that the material retains its strength and performance even after prolonged exposure to high temperatures, making it ideal for turbine engines and other high-performance machinery.


Melting
The alloy is melted using an electric arc or induction furnace, where high-purity raw materials are used to ensure the desired chemical composition. The molten metal is refined to remove impurities.
Casting
The refined molten metal is cast into ingots, which are subjected to homogenization heat treatments to eliminate segregation and enhance uniformity.
Forging
The ingots are hot-forged at temperatures above 1100°C, shaping the alloy into the desired form while refining the microstructure and improving mechanical properties.
Hot Rolling
The forged material undergoes hot rolling to achieve the final dimensions, reducing thickness and enhancing directional properties.
Annealing
The rolled bars are annealed at temperatures of 900-950°C to relieve internal stresses and improve ductility, making them easier to machine and fabricate.
Finishing
The final bars are cut to the required lengths and may undergo surface treatments like grinding, polishing, or coating to enhance performance and protect against environmental damage.
