Five common high-temperature alloy grades

1.GH4169 (Inconel 718):
GH4169 is a nickel-based superalloy that exhibits high strength, excellent fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, good processability, weldability, and long-term microstructural stability. It is widely used in the aerospace industry for components such as engine parts, gas turbines, and rocket engines. Additionally, it finds applications in nuclear energy and petrochemical industries.

2.GH3039 (Inconel 600):
GH3039 is a nickel-chromium-iron-based solid solution strengthened wrought superalloy with good oxidation resistance, corrosion resistance, and thermal fatigue resistance. It maintains satisfactory hot strength and high ductility below 700°C. It is primarily used in the manufacturing of components for aircraft engines and land-based gas turbines, such as combustion chambers and guide vanes.

3.GH3625 (Inconel 625):
GH3625 is a nickel-based alloy that demonstrates outstanding comprehensive properties within the temperature range of -253°C to 1000°C, including high strength, fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, along with excellent processability, weldability, and long-term microstructural stability. It is extensively applied in aerospace, aviation, petroleum, and chemical industries, particularly crucial for engine components, gas turbines, and nuclear reactors.

4，GH2132 (GH132):
GH2132 is an iron-based superalloy that boasts high-temperature strength, good hot workability, microstructural stability, and weldability. It is primarily employed in the production of high-temperature components for aircraft engines, such as turbine disks, compressor disks, blades, and fasteners.

5.GH5605 (GH605):
GH5605 is a nickel-based alloy renowned for its high-temperature strength, creep resistance, and oxidation resistance. It is particularly suited for manufacturing turbine outer rings, turbine casings, swirlers, and sealing strips in aircraft engines.
