GH3030

GH3030 is an early developed 80Ni-20Cr solid solution strengthened superalloy with simple chemical composition, satisfactory thermal strength and high plasticity below 800 ℃, and good oxidation resistance, thermal fatigue, cold stamping and welding process performance. The alloy is single-phase austenite after solution treatment, and its structure is stable during use. It is mainly used for turbine engine combustion chamber components working below 800 ℃ and other high-temperature components that require oxidation resistance but bear little load below 1100 ℃.
