The alloy is a modified alloy of IN 738 alloy. Compared with it, it not only has excellent heat and corrosion resistance of IN 738 alloy, but also increases the lasting strength by 20-50MPa and the service temperature by 20 ℃. The alloy has good microstructure stability and casting process properties.
The alloy has been used to make industrial gas turbine blades, offshore aircraft and ship gas turbine parts working under 900℃ for a long time.
