DC03 cold rolled steel sheet is a drawing-quality, low-carbon steel grade manufactured in accordance with EN 10130 (Steel Number: 1.0347). Known for its excellent dimensional precision, consistent mechanical properties, and reliable forming performance, DC03 is widely used in industries where both precision and durability are essential.
As a professional international supplier, GNEE STEEL provides high-quality DC03 cold rolled steel sheets tailored for automotive, home appliance, electrical, and general manufacturing applications.
What Makes DC03 Steel Sheet Precise and Durable?
DC03 steel is produced through cold rolling and controlled annealing, resulting in:
Tight thickness tolerances
Smooth and uniform surface finish
Stable yield strength
Enhanced ductility for forming
This combination ensures high processing accuracy and long-term performance in finished components.
Chemical Composition of DC03 Steel (Typical)
| Element | Max (%) |
|---|---|
| Carbon (C) | 0.08 |
| Manganese (Mn) | 0.40 |
| Phosphorus (P) | 0.025 |
| Sulfur (S) | 0.020 |
Low carbon and impurity levels contribute to stable forming behavior and improved durability in service.
Mechanical Properties Ensuring Reliable Performance
| Property | Typical Value |
|---|---|
| Yield Strength (Rp0.2) | ≤ 240 MPa |
| Tensile Strength (Rm) | 270–370 MPa |
| Elongation (A80) | ≥ 28% |
These properties allow DC03 steel sheets to maintain strength while accommodating plastic deformation, essential for precision-formed parts.

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.
