Short Description:

Solid solution strengthening type high-temperature alloy GH3030

Product Detail

Our Advantage

Product Tags

GH3030 is an early developed 80Ni-20Cr solid solution strengthened superalloy with simple chemical composition, satisfactory thermal strength and high plasticity below 800˚C, and good oxidation resistance, thermal fatigue, cold stamping and welding processes performance. The alloy is single-phase austenite after solution treatment, and the structure is stable during use. The main products are cold-rolled sheets, and deformed products such as bars, rings, wires and pipes can also be supplied. It is mainly used for turbine engine combustion chamber components that work below 800˚C and other high-temperature components that require oxidation resistance below 1100˚C but with little load. GH3030 has strong heat processing and cold processing performance, and is used to make various chemical equipment and supporting accessories.
