JSC270F (DC05) Super Deep Drawing Cold Rolled Steel Coil for Complex Curved Outer Panels with EN 10130 DC05 Equivalent

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
