Cold-rolled steel
Cold-rolled steel is widely used across automotive, manufacturing, electrical appliances, and precision-formed components due to its excellent surface quality, tight dimensional tolerances, and reliable mechanical performance. Among the many available grades, DC01 remains one of the most commonly used cold-rolled steels because it offers balanced strength, ductility, and excellent formability for general-purpose applications.
This article provides a complete technical overview of DC01 cold-reduced sheet, focusing on the popular product size 2500 × 1250 × 2.00 mm, including material characteristics, mechanical properties, dimensional tolerances, and common industrial uses.
DC01 Cold-Rolled Steel
1. What Is DC01 Cold-Rolled Steel?
DC01 is a low-carbon, cold-rolled steel grade specified for forming, bending, stamping, and general fabrication. It belongs to a family of cold-rolled sheet grades with controlled chemical composition and mechanical properties to ensure predictable forming behavior and high-quality surface finish.
Key characteristics of DC01 include:
- Consistent low carbon content for improved ductility
- Smooth surface suitable for painting, coating, and decorative finishes
- Tight thickness and dimensional tolerances
- Good uniformity across the steel sheet
- Suitable for bending, profiling, and moderate drawing operations
The cold-reduction process improves tensile strength and surface precision, making DC01 suitable for applications that require both strength and aesthetic quality.
The size 2500 × 1250 × 2.00 mm is a common industrial-format sheet suitable for metal fabrication, forming workshops, and OEM manufacturing processes.
Product Specification Table
| Parameter | Specification |
|---|---|
| Grade | DC01 (Cold-rolled) |
| Thickness | 2.00 mm |
| Width | 1250 mm |
| Length | 2500 mm |
| Manufacturing Process | Cold-reduced / cold-rolled |
| Surface Condition | Smooth, bright, suitable for coating |
| Edge Condition | Mill edge or cut edge |
| Tolerance Standard | Based on cold-rolled sheet dimensional standards |
This thickness and format offer an ideal balance between flexibility and strength, allowing forming without excessive cracking while maintaining rigidity for structural or panel applications.
2. Chemical Composition of DC01
DC01 is a mild steel with strictly controlled chemistry to ensure uniform forming quality.
Typical Chemical Composition
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.12 |
| Manganese (Mn) | ≤ 0.60 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.045 |
| Nitrogen (N) | ≤ 0.008 |
These limits result in a soft, formable steel that performs consistently in stamping, folding, and shallow drawing.
3. Mechanical Properties
Cold-rolling increases strength while maintaining ductility, making DC01 ideal for general-purpose cold forming.
Mechanical Property Table
| Property | Typical Value |
|---|---|
| Yield Strength | 140–280 MPa |
| Tensile Strength | 270–410 MPa |
| Elongation (A80) | ≥ 28% |
| Hardness | Approx. 45–65 HRB |
These properties apply to standard cold-rolled material before further heat treatment or annealing operations.
4. Dimensional Tolerances for 2.0 mm DC01 Sheet
Accurate tolerances are essential for manufacturing precision components.
Thickness & Width Tolerance Reference
| Parameter | Tolerance |
|---|---|
| Thickness (2.00 mm) | ±0.06 mm (typical cold-rolled tolerance) |
| Width (1250 mm) | ±5 mm |
| Camber | Within standard limits for cold-rolled sheet |
| Flatness | Highly controlled due to cold-reduction |
These tight tolerances minimize material waste and improve shaping consistency.
