Wrought Superalloy
GH3030 alloy
80Ni-20Cr Solid-solution strengthened high temperature alloy has simple
chemical composition. It has good anti-oxidation, heat resistant, cold
pressing and welding capability. It can work under 800℃ normally with
stable organization. It becomes single-phrase austenitic after solid-solution and can bear large stress for long time under high temperature.
