The alloy has good creep resistance, durability, cold and hot fatigue resistance, significantly improved room temperature plasticity and impact properties, and improved microstructure stability. This good comprehensive performance has great advantages in the application of integrally cast turbine.


The alloy has been used to manufacture rotor blades, turbine guides and integral rotors of aero-engine free turbines. The alloy has been widely used abroad, including making turbine guide, integral rotor and rotating blade of aeroengine, turbine disk of unmanned aircraft engine, and integral cast turbine of gas turbine for power generation for long-term use.
