💡 Key Repair & Operation Instructions:

Extreme Wear Resistance: High carbon-chromium composition forms dense chromium carbides, delivering 56–60 HRC hardness and high wear resistance for cold cutting edges and punches.
Preheating Requirement (TIG): SKD11 / D2 has very high hardenability and crack sensitivity. **Preheating to 350°C–450°C is critical** during TIG repair to prevent cold cracking and edge spalling.
