1. Introduction to GH3030 Materials
GH3030 solid solution reinforced high-temperature alloy is an early developed 80Ni-20Cr solid solution reinforced high-temperature alloy. It has simple chemical composition and has satisfactory thermal strength and high plasticity below 800℃. It also has good antioxidant, thermal fatigue, cold stamping and welding process performance. After solid solution treatment, the alloy is single-phase austenite, and the structure is stable during use. The main products are cold-rolled thin plates, which can also supply deformed products such as bars, rings, wires and pipes. Mainly used for turbine engine combustion chamber components that operate below 800°C and other high-temperature components that require oxidation resistance below 1100°C but bear very small loads. [1] GH3030 has strong hot processing and cold processing properties, and is used to make various chemical equipment and supporting accessories.
