Overview of EN 10130 DC Series Cold Rolled Steel
The DC series is classified mainly by formability.
As the grade number increases, the steel becomes softer, more ductile, and more suitable for deep drawing, while yield strength decreases.
Formability ranking:
DC01 → DC02 → DC03 → DC04 → DC05 → DC06
(From general forming to extra-deep drawing)

Performance Advantages Of Cold-rolled Low Carbon Steel
1. Excellent machining performance
Cold–rolled low carbon steel has excellent processing performance, suitable for deep drawing, bending, drawing and other processing operations. Its high ductility and excellent deep drawing performance make it particularly outstanding in stamping, bending and other forming processes.
Low carbon content makes the material not easy to crack and fracture in the processing process, effectively improve the production efficiency and yield.
2. High surface quality
The application of cold rolling process improves the surface finish and dimensional accuracy of the material, and can meet the needs of a variety of applications without additional surface treatment.
The smooth and uniform surface quality makes this steel can present a more delicate and beautiful appearance after spraying.
3. Excellent mechanical properties
It has high strength, high yield strength and high tensile strength, showing good bearing capacity and deformation resistance.
Large elongation means that when subjected to external forces, large plastic deformation can occur and it is not easy to break, which provides more possibilities for the design of complex structures.
4. High corrosion resistance and high strength
Usually after galvanizing or other surface treatment, its surface forms a protective layer, which provides good corrosion resistance.
It performs well in corrosion-prone applications such as Marine environments, chemical fields and outdoor structures.
5. Environmental performance
As a kind of low carbon and environmental protection steel, cold rolled low carbon steel has shown good environmental protection performance in the process of production and use.
The low carbon content reduces greenhouse gas emissions, while the cold rolling process can use energy more efficiently and reduce waste generation compared to the hot rolling process.

What is the difference between DC01 and DC04 steel?
DC04 and DC01 are both cold-rolled, unalloyed quality steels that are used for various industrial applications. While DC01 serves as the standard grade for general cold forming processes, DC04 is characterized by improved deep-drawing properties and higher ductility.
Is DC01 the same as CR4?
Cold Reduced steel
Here at GNEE Steel, we stock and process DC01 mild steel (often referred to as CR4), in varying thicknesses from 0.9mm up to 3mm. Each sheet is de-coiled and flattened to strict tolerances in our works, ensuring consistent quality and flatness, every time.
What does DC01 mean?
DC01 represents the basic grade of the DC steel family and is also known under the former designations St12 or FeP01. This grade can be used for simple forming operations such as bending, coining, beading and drawing.
What is the difference between DC01 and DC03?
DC01 – This grade can be used for simple forming work, e.g. bending, embossing, beading and drawing. DC03 – This grade is suitable for forming requirements such as deep drawing and difficult profiling.
What is DC01 steel equivalent to?
Material 1.0330, DC01 steel equivalent to ASTM, ISO, European (German DIN, British BSI, France NF), Japanese JIS and Chinese GB standard (for reference). Note: DIN 1623 has been replaced by DIN EN 10130, and the designation ST12 has been replaced by DC01.
What is the thickness of DC01 material?
Galvanized Steel Sheet - Grade Dc01, Thickness 0.2-3.50mm, Width 914-1250mm | Cold Rolled, Durable Zinc Coating, Long Lasting Toughness.
Is cold-rolled steel better than hot rolled steel?
Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than hot rolled through the use of strength hardening.
