Features

The alloy has good microstructure temperature, high temperature oxidation resistance and heat-resistant corrosion resistance. The sampling performance of parts is close to that of single cast samples, and the dispersion of performance data is small. The alloy has good casting process performance, but because it contains more tungsten, tantalum and hafnium elements, it has higher density than other equiaxed cast nickel base superalloys.

Applications

The alloy has been used to make working blades of pressure cooker turbine and integrally cast turbine of aeroengine.
