1. Brief introduction:

   It has quite good combination property during -253~700℃. Its yield strength ranks the first among deformation super alloy when the temperature is below 650℃.

   The alloy has quite good fatigue strength, anti-radiation, antioxidant property, corrossion resistant performance, and machining, welding performance and long-term structure stability.

   It can be made into complicated shaped components, and has been widespread used in space navigation, nuclear energy and petrochemical industry.
