Cold Rolled Steel
Manufacturers of home appliances and precision metal stamping components frequently compare DC06 and DC04 cold rolled steel when choosing materials for deep drawing applications. Both grades belong to high-quality cold rolled steel, but their forming performance differs significantly in critical applications. Global buyers searching for cold rolled steel sheet price, rolled steel suppliers, and cold rolled steel products increasingly focus on DC06 because it offers greater resistance to wrinkling and cracking during extreme forming.
📌 DC04 Cold Rolled Steel - for standard deep drawing
📌 DC06 Cold Rolled Steel - for extra-deep drawing under severe deformation
DC06 vs DC04 Cold Rolled Steel - Performance Comparison Table
| Comparison Item | DC04 Cold Rolled Steel | DC06 Cold Rolled Steel |
|---|---|---|
| Steel Type | Cold rolled steel for deep drawing | Cold rolled steel for extra-deep drawing |
| Elongation | High | Very high (higher than DC04) |
| Formability | Suitable for standard deep drawing | Suitable for complex and extreme deep drawing |
| Tensile Strength | Slightly higher | Lower (improves formability) |
| Yield Strength | Higher | Lower, reducing the risk of cracking |
| Risk of Cracking During Large Deformation | Moderate | Very low |
| Tooling Complexity | Compatible with conventional molds | Compatible with advanced multi-curvature tooling |
| Typical Applications | Appliance panels, general stamped parts, electronics housings | Automotive exterior panels, fuel tanks, inner structural panels, deep-drawn appliance housings |
| Surface Treatment Compatibility | Good | Excellent, supports powder coating, galvanizing, e-coating, and automotive painting |
| Production Defect Rate | Moderate | Lower (less wrinkling and springback issues) |
| Cost Level | Economical | Slightly higher but reduces manufacturing scrap and tooling wear |
| Recommended Use Case | Products requiring standard shape accuracy | High-precision components requiring extreme drawability and perfect surface appearance |
If the product requires multiple stamping, deep cylindrical forming, or a mirror-like coated surface, DC06 provides greater stability and significantly reduces rejection rates-especially for large appliance parts, industrial housings, and automotive body components.
DC06 also has better weldability and post-forming elasticity than hot rolled sheet or rolled sheet metal. It supports surface finishing from electrostatic powder coating to galvanizing, making it a popular substitute for cold rolled stainless steel sheet in applications that do not require corrosion-resistant stainless steel.
