GH3030 solid solution reinforced superalloy is an early 80Ni-20Cr solid solution strengthened superalloy. It has simple chemical composition, satisfactory thermal strength and high plasticity below 800℃, and good oxidation resistance, thermal fatigue, cold stamping and welding process properties.
After solution treatment, the alloy is single phase austenite, and the structure is stable during use.
Turbine engine combustor components to be used for work below 800℃ and other high-temperature components that require oxidation resistance but bear little load below 1100℃.
GH3030 has strong performance of hot processing waste cold processing, used for making various chemical equipment and accessories.
