TECHNICAL DATA SHEET (TDS) & PROCESS GUIDE Standard: AISI 420 / DIN 1.2083 / JIS SUS420J2
1. Chemical Composition (wt%)
| Element | C | Si | Mn | Cr | V | Fe |
|---|---|---|---|---|---|---|
| Specification | 0.35–0.45 | 0.30–0.80 | 0.30–0.80 | 12.00–14.00 | 0.20–0.40 | Balance |
2. Welding Parameters: Laser vs. TIG
⚡ Laser Welding 0.15–0.6 mm
| Preheat Temp | Room Temp – 100°C |
| Pulse Power | 120–220 A |
| Shielding Gas | Argon ≥99.99% (3–6 L/min) |
| HAZ Impact | Extremely low HAZ, prevents Cr depletion |
🔥 TIG Welding 0.8–2.4 mm
| Preheat Temp | 250°C – 350°C Mandatory |
| Welding Current | 35–100 A (DCEN) |
| Shielding Gas | Argon ≥99.99% (8–12 L/min) |
| Post-Heat | Slow cooling in insulation blanket |
💡 Key Repair & Operation Instructions:
- High Corrosion Resistance: High chromium content (~13% Cr) protects repaired areas against corrosive resins (PVC, UP, acid-releasing plastics) and damp ambient conditions.
- Crack Prevention (TIG): Martensitic stainless steel S136 is crack-sensitive during TIG repair. **Preheating to 250°C+ is critical** to prevent cold cracking.
