SKD11 Cold Work Die Steel,flat steel,alloy
SKD11
High wear-resistant cold working die steel
Specialty:
1. Vacuum degassing refining steel, pure endoplasm
2. Good mechanical processing (increase 20% than SKD1 in machinability)
3. Good harden ability (difficult to appear the quenching crack)
4. Excellent abrasion resistance (apply to the blanking die of stainless steel and high hardness materials)
5. Good toughness
