Corresponding to other steel mill grades：SLD DC11 XW-41 1.2379
Specialty：
- A maximum hardness of 62 HRC increases wear resistance by about 35%
- Adhesion of surface treatment films (CVD etc.) increased by about 30%
- The heat treatment change is reduced by about 40%, and the shape deviation will also improve
- Cutting about 35%
