Product Description
JSC270F (DC05) Super Deep Drawing Steel Coil for Complex Curved Outer Panels
JSC270F is an EN 10130 DC05-equivalent cold-rolled steel coil optimized for deep drawing applications requiring extreme formability. With exceptional elongation (≥34%) and controlled anisotropy (r-value ≥1.8), it enables seamless fabrication of high-curvature body panels like fenders and wheel arches while reducing scrap rates by 20% versus conventional deep-drawing steels.

Core Engineering Advantages
1. Superior Formability for Complex Geometries
- Deep Drawing Capability: Achieves LDR ≥2.5 (Limiting Drawing Ratio), enabling 65 mm dome depths for fender crowns without cracking
- Springback Control: 73% lower angular deviation (0.6° vs. 2.2°) versus mild steel, ensuring dimensional accuracy in curved panels
2. Surface-Sensitive Performance
- Paint Adhesion: Optimal surface roughness (Ra 0.8-1.2 μm) guarantees Class A coating appearance after E-coat
- Corrosion Resistance: Zinc coating option (60-90 g/m²) provides >1,200 hours salt spray resistance
3. Manufacturing Efficiency
- Stamping Yield: >98% success rate for panels with 12% stretch flanging
- Tooling Economy: 67% longer die life (500,000+ cycles) due to low abrasive wear
