Cold Rolled Steel Plate
Cold rolled steel plate plays a crucial role in modern manufacturing, especially in industries that demand high surface quality, tight dimensional tolerance, and stable mechanical performance. Among the most widely used cold rolled steel grades, DC01, DC03, DC04, DC05, DC06, and DC07 defined under EN 10130 are commonly selected for applications ranging from basic structural components to complex deep-drawing parts.
What Is Cold Rolled Steel Plate?
Cold rolled steel plate is produced by further processing hot rolled steel through cold reduction at room temperature. This process significantly improves surface finish, thickness accuracy, and mechanical consistency. Compared with hot rolled steel, cold rolled grades offer smoother surfaces, better flatness, and enhanced formability, making them ideal for precision stamping, bending, and forming operations.
Overview of DC01–DC07 Cold Rolled Steel Grades
The DC series represents non-alloy cold rolled low-carbon steel grades, primarily distinguished by their forming capability. As the grade number increases from DC01 to DC07, the steel's deep-drawing performance improves.
| Grade | Forming Capability | Typical Applications |
|---|---|---|
| DC01 | Basic forming | Panels, brackets, general fabrication |
| DC03 | Improved forming | Light stamping, appliance shells |
| DC04 | Deep drawing | Automotive inner parts |
| DC05 | Extra deep drawing | Complex stamped components |
| DC06 | Special deep drawing | Precision automotive parts |
| DC07 | Ultra-deep drawing | Advanced forming applications |
DC01 vs DC03 – Key Differences
Among all cold rolled grades, DC01 and DC03 are the most frequently compared due to their wide availability and overlapping applications.
| Property | DC01 | DC03 |
|---|---|---|
| Yield Strength (MPa) | ≤ 280 | ≤ 240 |
| Tensile Strength (MPa) | 270–410 | 270–410 |
| Elongation (%) | ≥ 28 | ≥ 34 |
| Formability | Basic | Improved |
| Typical Use | Flat parts | Light deep drawing |
DC01 cold rolled steel plate is suitable for simple bending and flat forming processes, while DC03 cold rolled steel plate offers better elongation and reduced risk of cracking during stamping. Manufacturers producing appliance housings or light automotive components often upgrade from DC01 to DC03 to improve forming reliability without significantly increasing cost.
Thickness, Width, and Supply Range
Cold rolled steel plates in DC grades are commonly supplied in thicknesses from 0.3 mm to 3.0 mm, with widths up to 1850 mm, available in coils, sheets, or cut-to-length plates. Surface finishes such as bright finish, oiled, or dry are selectable based on customer requirements.
Applications Across Industries
DC01–DC07 cold rolled steel plates are widely used in:
- Automotive body and interior components
- Home appliances such as refrigerators and washing machines
- Electrical cabinets and control panels
- Furniture frames and metal enclosures
