GH3030 material description:
80Ni-20Cr solid solution strengthening superalloy has simple chemical composition, satisfactory thermal strength and high plasticity below 800 C, and good oxidation resistance, thermal fatigue, cold stamping and welding process properties. The alloy is single phase austenite after solid solution treatment, and its structure is stable during use.
GH3030 Material Uses:
It is mainly used for turbine engine combustor components working below 800 C and other high temperature components requiring oxidation resistance below 1100 C but with little load.
