Product features

GH4049 is a Ni-Co-Cr-based precipitation-hardening wrought superalloy with a service temperature below 950°C. The alloy possesses good oxidation resitance below 1000°C and high high-temperature strength below 950°C. It is suitable for manufacturing gas turbine working blades operating at temperatures ben 850°C and 950°C. Major products include hot-rolled and forged bars, and die-forged turbine blades. Compared with nickel-based alloys of similar application, ths relatively poor hot workability; however, its workability can be improved through electroslag remelting or vacuum arc remelting, and the impact tougness at 1000°C-1170°C is increased by 1 to 3 times.

Application scope domain

Alloys have been used to manufacture aircraft engine turbine blades and other high-temperature load-bearing components, and after long-term manufacturing and application, they have become one most widely used materials for blades.
