Product Features

GH4049 is a Ni Co Cr based precipitation hardening deformation high-temperature alloy, used at temperatures below 950 ° C; C， This alloy is priced at 1000; C and below have good antioxidant properties, 950; C and below have high high-temperature strength. Suitable for producing gas turbine blades with working temperatures ranging from 850 ° C to 950 ° C. The main products include hot-rolled and forged bars, as well as forged turbine blades. Compared with nickel based alloys for similar applications, this alloy has poor hot working plasticity. However, after electric slag remelting or vacuum arc remelting, its processing plasticity can be improved, and the impact toughness at 1000 ° C-1170 ° C can be increased by 1-3 times.

Application scope and field

Alloy has been used to manufacture aircraft engine turbine blades and other high-temperature load-bearing components. After long-term manufacturing and application, it has become one of the most widely used blade materials.
