1. Chemical Composition (wt%)
| Element | C | Si | Mn | Cr | Mo | V | Fe |
|---|---|---|---|---|---|---|---|
| Specification | 1.40–1.60 | 0.10–0.60 | 0.20–0.60 | 11.50–13.00 | 0.70–1.20 | 0.20–1.00 | Balance |
2. Welding Parameters: Laser vs. TIG
⚡ Laser Welding 0.2–0.6 mm
| Preheat Temp | Room Temp – 100°C |
| Pulse Power | 110–210 A |
| Shielding Gas | Argon ≥99.99% (3–6 L/min) |
| HAZ Impact | Minimal HAZ, ideal for delicate edge repair |
🔥 TIG Welding 0.8–2.4 mm
| Preheat Temp | 350°C – 450°C Mandatory |
| Welding Current | 40–110 A (DCEN) |
| Shielding Gas | Argon ≥99.99% (8–12 L/min) |
| Post-Heat | Slow cooling or 500°C stress relief annealing |
💡 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.
