Cold Rolled Steel
What Is Cold Rolled Steel?
Cold rolled steel is manufactured by further rolling hot rolled steel at room temperature after surface descaling. This process improves surface smoothness, thickness accuracy, flatness, and mechanical consistency. Compared with hot rolled steel, cold rolled steel sheet and coil are better suited for precision forming, coating, and appearance-sensitive applications.
DC01 is one of the most commonly specified cold rolled steel grades under the EN 10130 standard. It is designed for general cold forming and offers a reliable balance between formability, strength, and cost efficiency.

Understanding the DC01 Steel Grade
The designation DC01 follows a standardized naming system:
- D – Flat steel products for cold forming
- C – Cold rolled
- 01 – Commercial quality grade
DC01 steel plate and sheet are intended for bending, profiling, and shallow drawing operations. Because of its stable performance, DC01 cold rolled steel is widely used in mass production environments.
DC01 Material Specification Overview
The material specification of DC01 defines its chemical composition and mechanical properties to ensure consistent processing performance:
| Item | Specification |
|---|---|
| Standard | EN 10130 |
| Product Form | Cold rolled sheet and coil |
| Surface Quality | Smooth, suitable for coating |
| Forming Type | General cold forming |
This specification makes DC01 suitable for stamping, bending, and secondary surface treatments such as galvanizing and painting.
Chemical Composition of DC01 Steel
DC01 is classified as a low-carbon steel. Typical chemical limits are shown below:
| Element | Maximum Content (%) |
|---|---|
| Carbon (C) | 0.12 |
| Manganese (Mn) | 0.60 |
| Phosphorus (P) | 0.045 |
| Sulfur (S) | 0.045 |
Low carbon content improves ductility and weldability, reducing the risk of cracking during forming.
DC01 Yield Strength and Mechanical Properties
DC01 yield strength is a key parameter in material selection. Under EN 10130, DC01 typically has a yield strength of ≤ 280 MPa, making it suitable for general forming applications.
| Mechanical Property | Typical Value |
|---|---|
| Yield Strength | ≤ 280 MPa |
| Tensile Strength | 270–410 MPa |
| Elongation | ≥ 28% |
This combination allows DC01 cold rolled steel sheet to be formed efficiently without excessive springback or deformation resistance.
DC01 Compared with Other Cold Rolled Steel Grades
DC01 is often compared with higher-formability grades:
| Grade | Formability Level | Typical Applications |
|---|---|---|
| DC01 | General forming | Panels, brackets |
| DC02 | Improved forming | Moderate drawing |
| DC03 | Deep drawing | Complex stamped parts |
| DC04–DC06 | Extra deep drawing | Automotive panels |
DC01 remains the most economical choice when deep drawing is not required.
Typical Applications of DC01 Steel
DC01 cold rolled steel is widely used in:
- Home appliance housings
- Electrical enclosures
- Metal furniture components
- Automotive interior parts
- Construction accessories
Its smooth surface quality makes it ideal for painted and coated products.
