GNEE Superalloy GH3030 Pipe
GH3030 is a solid solution strengthened high temperature alloy developed in the early stage. It is a 80Ni-20Cr solid solution strengthened high temperature alloy with simple chemical composition. It has good thermal strength and plasticity below 800℃, and has good oxidation resistance, thermal fatigue resistance, cold stamping performance and welding process performance. After solid solution treatment, it is single-phase austenite, and the organization is stable during use.
