DP1000 is a premium dual-phase advanced high-strength steel (AHSS) delivered in precision cold-rolled coil form. Engineered specifically for automotive safety-critical components, it delivers exceptional strength-ductility balance to meet rigorous crash performance standards while enabling significant lightweighting.
| Parameter | Value |
|---|---|
| Grade Standard | EN 10346 / ASTM A1008 |
| Tensile Strength | 1000 MPa (min) |
| Yield Strength | 600-850 MPa |
| Elongation (A80mm) | ≥10% |
| Thickness Range | 0.8-2.5 mm (±0.05 mm tolerance) |
| Width Range | 800-1850 mm (±1 mm tolerance) |
| Surface Finish | Class A (Zero Defect, Oiled) |
Microstructure: Dual-phase (80% martensite + 20% ferrite) enables controlled deformation during side impacts, absorbing >35% more energy than HSS grades.
Crash Test Validation: Meets Euro NCAP 5-star & IIHS Top Safety Pick+ requirements for side-pole impact.
Replaces traditional 600MPa steels with 25% thickness reduction (e.g., 1.8 mm → 1.35 mm), achieving ~15% weight savings per door.
Cold Formability: High n-value (≥0.16) and r-value (≥1.0) allow complex U-shaped beam stamping without cracking.
Weldability: Low carbon equivalent (Ceq ≤0.25%) enables seamless resistance spot welding at 6.5 kA.
Optional Zinc Coating (GI/GA) available for extended service life (>10 years salt spray resistance).
| Property | DP1000 | Conventional Steel | Improvement |
|---|---|---|---|
| Peak Load Capacity | 42 kN | 32 kN | +31% |
| Intrusion Distance | ≤150 mm | ≥220 mm | ↓32% |
| Fatigue Cycles (10) | Pass | Fail at 0.8×10 | +25% |
