DC06 is already considered an ultra-deep-drawing steel used extensively in automotive interior components and complex industrial stampings. However, DC07 represents the highest formability level in the EN 10130 series, making it the preferred choice for the most challenging forming operations.
DC06 vs DC07: Understanding the Final Step Up
DC06 provides excellent ductility and very low yield strength. However, DC07 pushes these parameters further, allowing components to undergo extreme deformation without defects.
| Property | DC06 | DC07 |
|---|---|---|
| Standard | EN 10130 | EN 10130 |
| Grade Level | Ultra-deep-drawing | Superior ultra-deep-drawing |
| Yield Strength | Very low | Lowest of all DC grades |
| Elongation | Very high | Highest level |
| Formability | ★★★★★ | ★★★★★★ |
| Application | Air-conditioning panels, automotive brackets | Highly complex, multi-stage components |
Key Reasons DC07 Surpasses DC06
Ideal for Extreme Geometries
When DC06 reaches its forming limit, DC07 continues to maintain stability.
Better Quality in Multi-Stage Operations
DC07 reduces cracking during redrawing or ironing processes.
Supports Higher Production Efficiency
Its consistent mechanical behavior helps reduce die wear and material failure.
DC07 is the best choice when the forming application exceeds the limits of DC06.
