Product FEATURE
GH4049 is a Ni-Co-Cr based precipitation hardening deformation high temperature alloy with a service temperature of less than 950℃. The alloy has good oxidation resistance under 1000℃ and high high temperature strength under 950℃. It is suitable for the production of gas turbine working blades with operating temperature of 850℃~950℃. The main products include hot rolled and forged bars, and die forged turbine blades. Compared with nickel-based alloys of similar applications, the alloy's hot working plasticity is poor, but after electroslag remelting or vacuum arc remelting, its processing plasticity can be improved, and the impact toughness of 1000 ℃ -1170 ℃ increased by 1 ~ 3 times.
Product application
The alloy has been used in the manufacture of aircraft engine turbine blades and other high-temperature load-bearing components. After a long period of manufacturing and application, it has become one of the most widely used foliage materials.
