  Metallographic structure:

  The alloy is single-phase austenite in a solid solution state and contains a small amount of Ti (CN), NbC, and M23C6 carbides.

  
  

  Process performance requirements:

  1. This alloy has good hot working plasticity and good deformation performance. The forging heating temperature is 1170 ℃, and the final forging temperature is 900 ℃.

  
  

  2. The average grain size of this alloy is closely related to the degree of deformation of the forging and the final forging temperature.

  
  

  3. Alloys can be welded using argon arc welding, spot welding, or seam welding methods, with excellent welding performance and low tendency for cracks in argon arc welding.

  
  

  4. After heat treatment, the surface oxide skin of the parts can be removed by sand blowing or acid washing methods.
