In the steel industry, DC01, DC02, DC03, and DC04 cold rolled steel plates are widely used in automotive, construction, and household appliance manufacturing. Buyers often ask: What is the difference between DC01 and DC04? Which grade is better for deep drawing?

This article explains the properties, applications, and differences of these cold rolled steel grades to help engineers, buyers, and manufacturers make the right choice.

What is Cold Rolled Steel Plate?

Cold rolled steel plate is produced by further processing hot rolled steel under cold reduction. This process improves surface finish, dimensional accuracy, and mechanical strength, making it suitable for precision forming and welding applications.

DC01 / DC02 / DC03 / DC04 Steel Properties

👉 Key point: The lower the yield strength, the better the steel can be deformed without cracking.

Applications of DC01 – DC04 Cold Rolled Steel Plates

• Automotive Industry: Body panels, seat structures, crash-reinforced parts.

• Household Appliances: Washing machine panels, refrigerators, oven parts.

• Construction & Engineering: Cladding, electrical cabinets, and industrial equipment.

• Precision Components: Stamping, embossing, and deep drawing parts requiring smooth surfaces.

DC01 vs DC04: Which One Should You Choose?

• Choose DC01 if you need general stamping, bending, or forming.

• Choose DC02 / DC03 if your project involves deeper drawing with higher shape complexity.

• Choose DC04 if you need maximum formability and deformation resistance, for example in complex automotive panels.

Advantages of DC01 – DC04 Cold Rolled Steel Plate

• Excellent weldability and machinability

• Smooth surface finish for painting and coating

• Wide range of dimensions and thicknesses

• Eco-friendly production with low carbon emissions

Conclusion

When comparing DC01, DC02, DC03, and DC04 cold rolled steel plates, the right grade depends on your forming requirements. For simple stamping, DC01 is cost-effective. For deep drawing and high deformation, DC04 is the best choice.
