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 process 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 produces turbine engine combustor components that work below 800°C and other high-temperature components that require oxidation resistance below 1100°C but with little load.
