DC03 Steel Chemical Composition
What Is DC03 Cold Rolled Steel?
DC03 is a low-carbon cold rolled steel grade specified in EN 10130, positioned between basic commercial-quality steels and deep-drawing grades. Compared with DC01, DC03 offers improved ductility and forming stability, while remaining more cost-effective and easier to process than higher-grade deep drawing steels such as DC05.
DC03 is particularly valued for applications that require:
- Reliable bending performance
- Moderate to improved drawing capability
- Stable surface quality
- Consistent mechanical properties across coils
These characteristics make DC03 one of the most widely used cold rolled steel grades in global manufacturing.
Packaging and shipping
DC03 is mainly used for stamping, such as auto parts and electrical appliances parts.

DC03 steel sheet and strip are usually coated oil supply, the applied film should be able to get rid of an alkaline aqueous solution, for guarantees from the date of manufacture under normal non-naked bag packaging, transportation, handling and storage conditions are not born six months rust. According to the requirements, and agreement by both sides in the contract, but also may not be coated with oil supply.
