Cold rolled steel
Cold rolled steel is widely used in automotive parts, household appliances, precision instruments and deep-drawn housings. Under EN 10130, grades DC01 to DC07 represent increasing levels of formability. Among them, DC07 stands at the top, designed for the most challenging ultra-deep drawing applications.
Overall Comparison - DC01 to DC07
| Grade | Formability Level | Suitable Forming Depth | Typical Use |
|---|---|---|---|
| DC01 | ★ | Basic forming | Simple stamped parts |
| DC03 | ★★★ | Mild drawing | Appliance parts |
| DC04 | ★★★★ | Deep drawing | Automotive brackets |
| DC05 | ★★★★★ | Extra deep drawing | Large panels |
| DC06 | ★★★★★½ | Ultra-deep drawing | Automotive interiors |
| DC07 | ★★★★★★ | Extreme geometric forming | Precision complex housings |
Why DC07 Leads the Series
- Highest Elongation
Essential for extreme forming depth and narrow radii.
- Lowest Yield Strength
Allows smooth material flow during deformation.
- Best Performance in Multi-Stage Drawing
Ideal for redrawing, ironing, flanging and stretching.
Applications Where DC07 Dominates
- Automotive interior housings
- Precision components with complex shapes
- Thin-gauge, deep-drawn electronics shells
- Multi-stage progressive die stamping
