TECHNICAL DATA SHEET (TDS) & PROCESS GUIDE Standard: Daido NAK80 / AISI P21 (Pre-hardened Age-Hardened Steel)
1. Chemical Composition (wt%)
| Element | C | Mn | Ni | Al | Cu | Mo | Fe |
|---|---|---|---|---|---|---|---|
| Specification | 0.12–0.20 | 1.40–1.70 | 2.80–3.20 | 0.80–1.10 | 0.90–1.20 | 0.20–0.40 | Balance |
2. Hardness & Welding Parameters
⚡ Laser Welding 0.15–0.6 mm
| Preheat Temp | Room Temp – 100°C |
| Pulse Power | 110–200 A |
| Shielding Gas | Argon ≥99.99% (3–5 L/min) |
| HAZ Impact | Ultra-smooth deposit matching parent steel hardness |
🔥 TIG Welding 0.8–2.4 mm
| Preheat Temp | 150°C – 200°C Recommended |
| Welding Current | 35–100 A (DCEN) |
| Shielding Gas | Argon ≥99.99% (8–10 L/min) |
| Post-Heat Relief | Slow natural cooling |
💡 Key Repair & Operation Instructions:
- Age-Hardening Feature: Reaches 37–43 HRC directly upon deposit, completely eliminating hard spots and boundary lines during EDM and mirror polishing.
- Mirror Finish Guard: High purity wire composition ensures zero porosity or micro-pinholes under high-magnification polishing.
