Process performance
1. The alloy has good malleability, forging heating temperature 1180℃, final forging 900℃.
2. The average size of the grain size of the alloy is closely related to the degree of deformation of the forging, final forging temperature.
3. After heat treatment, parts surface oxidation skin can be blown sand or acid cleaning method to delete.
