Cold Rolled Steel
Cold rolled steel plate is a core material for manufacturers seeking consistency, surface quality, and excellent forming performance. The DC01 to DC07 cold rolled steel grades under EN 10130 offer a progressive range of mechanical properties tailored for different forming depths and production complexities.
Mechanical Performance of DC Series Cold Rolled Steel
As the steel grade advances from DC01 to DC07, carbon content remains low, while grain structure and processing control enhance ductility. This makes higher grades particularly suitable for deep drawing operations where material flow and strain distribution are critical.
| Grade | Yield Strength (MPa) | Elongation (%) | Drawing Performance |
|---|---|---|---|
| DC01 | ≤ 280 | ≥ 28 | Basic |
| DC03 | ≤ 240 | ≥ 34 | Improved |
| DC04 | ≤ 210 | ≥ 38 | Deep drawing |
| DC05 | ≤ 180 | ≥ 40 | Extra deep drawing |

DC03 vs DC04 – Which One Should You Choose?
What is DC03 steel?
DC03 is a low-carbon steel characterized by excellent cold formability. The chemical composition of DC03 is precisely defined to ensure that the material has the required mechanical properties. Typically, DC03 contains a maximum of 0.10% carbon, a maximum of 0.45% manganese and traces of phosphorus and sulphur. This small amount of alloying elements contributes to the good formability and weldability of the steel.
The mechanical properties of DC03 are also clearly defined. The material has a yield strength of at least 140 MPa and a tensile strength of between 270 and 370 MPa. In addition, DC03 has an elongation at break of at least 34%, which underlines its excellent formability. These properties make DC03 particularly suitable for the production of complex components that require high precision and surface quality, such as body parts in the automotive industry or household appliances.
What is DC04 steel?
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.
The mechanical properties of DC04 are characterized by a low yield strength of maximum 210 MPa and a tensile strength between 270 and 350 MPa. Particularly noteworthy is the high elongation at break of at least 38%, which illustrates the excellent formability of the material. These properties make DC04 a preferred choice for the production of complex components that require high precision and surface quality, such as car body components in the automotive industry or filigree parts in the electronics industry.
The comparison between DC03 cold rolled steel plate and DC04 cold rolled steel plate often arises in automotive and appliance manufacturing.
| Aspect | DC03 | DC04 |
|---|---|---|
| Yield Strength | Higher | Lower |
| Elongation | Moderate | Higher |
| Surface Quality | Good | Excellent |
| Typical Application | Appliance housings | Automotive inner panels |
DC04 cold rolled steel plate is specifically designed for deep drawing, reducing the risk of tearing and surface defects. When production involves complex shapes or multiple forming stages, DC04 provides higher process stability than DC03.
