Cold Rolled Steel Plate
In forming-intensive industries, choosing the correct cold rolled steel grade is essential. The DC01 DC03 DC04 DC05 DC06 DC07 cold rolled steel plate series offers manufacturers flexible solutions for varying levels of stamping complexity and drawing depth.
Cold-rolled flat steel products play a central role in the modern manufacturing industry, especially in the field of cold forming. To ensure the quality and consistency of these products, specific standards are of crucial importance. The standards DIN EN 10130 and DIN EN 10152 define the requirements for these products and provide a framework for their manufacture and use. The grades within these standards are classified according to the maximum permissible yield strength and can be subdivided as follows.
| 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 |
Formability as the Core Difference
While all DC grades share low carbon content and fine surface finish, their deep-drawing capability is the defining factor. Higher grades undergo stricter process control to ensure uniform grain size and improved plastic deformation behavior.
DC04 vs DC05 – Extra Deep Drawing Performance
- What is DC04 steel?
The special deep-drawing grade DC04 is specified in accordance with the standard DIN EN 10130, which focuses on cold-rolled flat products made of soft steels for cold forming. This standard specifies the technical requirements and test methods for cold-rolled products that are important in numerous industrial applications, especially where high formability and excellent surface quality are required.
DC04 is a low-carbon steel that impresses with its exceptional cold formability. The chemical composition of DC04 is precisely balanced to ensure that the material has the desired mechanical properties. The carbon content in DC04 is typically a maximum of 0.08 %, while the manganese content is a maximum of 0.40 %. This composition supports the high formability and weldability of the steel, making it ideal for demanding forming processes.
- What is DC05 steel?
DC05 is a low-carbon steel that is characterized by its excellent cold formability. The chemical composition of DC05 is strictly controlled to ensure that the material has the desired mechanical properties. The carbon content in DC05 is typically a maximum of 0.02 %, while the manganese content is a maximum of 0.25 %. This composition promotes the high formability and weldability of the steel.
| Property | DC04 | DC05 |
|---|---|---|
| Yield Strength (MPa) | ≤ 210 | ≤ 180 |
| Elongation (%) | ≥ 38 | ≥ 40 |
| Drawing Capability | Deep drawing | Extra deep drawing |
| Typical Use | Automotive panels | Complex stamped shells |
DC05 cold rolled steel plate is ideal for parts with severe deformation, such as multi-stage drawn components or thin-wall stamped products. Compared with DC04, DC05 offers greater safety margins during forming, reducing scrap rates.
Where DC06 and DC07 Fit In
For the most demanding applications, DC06 and DC07 cold rolled steel plates provide superior consistency and ultra-deep drawing performance. These grades are commonly used in:
High-end automotive components
Precision electronic housings
Specialized industrial enclosures
