High-temperature Alloy Metal Manufacturer in China
GH80A（4080A）
GH80A is a high-temperature alloy based on nickel-chromium, with aluminum and titanium added to form R-phase dispersion strengthening. Except for the slightly higher aluminum content, it is similar to GH4033. Its operating temperature is 700~800℃, and it has good performance at 650~850℃. Creep properties and oxidation resistance.
GH90(4090)
GH90 is a NI-CR-CO-based precipitation hardening deformed high-temperature alloy with a service temperature of up to 920°C. Containing a relatively high amount of cobalt and a variety of strengthening elements, the alloy has high tensile strength and creep resistance at 815 to 870°C, good oxidation resistance and corrosion resistance, and has greater resistance to cold and heat under repeated alternating effects. High fatigue strength and good processing and welding properties.
GH3030
GH3030 is an 80Ni-20Cr solid solution strengthened super alloy with simple chemical composition, satisfactory thermal strength and high plasticity below 800 °C, and good oxidation resistance, thermal fatigue, cold stamping, and welding process performance. This alloy is monocrystalline austenite after solution treatment, and the structure is stable during use.
GH3039
GH3039 is a single-phase austenitic solid solution strengthened alloy with moderate thermal strength and good thermal fatigue properties below 800°C, and good oxidation resistance below 1000°C. The structure is stable after long-term use, and it also has good cold formability and welding performance. Suitable for long-term use of aircraft engine combustion chamber and afterburner components below 850°C. The alloy can be used to produce sheets, rods, wires, tubes and forgings.
GH5188
GH5188 alloy is a solid solution strengthened cobalt-based high-temperature alloy with carbide as the main strengthening phase. Compared with nickel-based superalloys, this alloy has better creep resistance, hot corrosion resistance, thermal fatigue resistance and high temperature strength. In the 1980s, GH5188 alloy was used in vortex plates, flame directors and other components of turboshaft eight-jet aero engines; currently, some aerospace engines use GH5188 alloy plates to prepare high-temperature components such as combustion chamber walls, outer walls, and sealing sheets. GH5188 alloy is a deformed cobalt-based high-temperature alloy with a simple microstructure
