TECHNICAL DATA SHEET (TDS) & PROCESS GUIDE Standard: AISI P20+Ni / DIN 1.2738 / GB 3Cr2NiMo
1. Chemical Composition (wt%)
| Element | C | Si | Mn | Cr | Mo | Ni | Fe |
|---|---|---|---|---|---|---|---|
| Specification | 0.33–0.41 | 0.20–0.40 | 1.20–1.50 | 1.80–2.10 | 0.15–0.35 | 0.90–1.20 | Balance |
2. Welding Parameters: Laser vs. TIG
⚡ Laser Welding 0.15–0.6 mm
| Preheat Temp | No preheat required |
| Pulse Power | 100–190 A |
| Shielding Gas | Argon ≥99.99% (3–5 L/min) |
| HAZ Impact | Ultra-narrow HAZ, zero sink marks |
🔥 TIG Welding 0.8–2.4 mm
| Preheat Temp | 180°C – 220°C recommended |
| Welding Current | 40–110 A (DCEN) |
| Shielding Gas | Argon ≥99.99% (8–12 L/min) |
| Post-Heat | Slow cooling in still air |
💡 Key Repair & Operation Instructions:
- Nickel Advantage: Addition of ~1.0% Nickel prevents soft spots and ensures uniform 33–38 HRC hardness even when welding deep cavities or thick-walled molds.
- Photo-Etching & Texturing: Excellent graining and chemical etching compatibility, leaving no visible boundary halos.
