Overview of Cold Rolled Mild Steel Materials
Cold rolled mild steels are low-carbon, non-alloy steels processed through cold rolling to achieve:
Precise thickness tolerance
Smooth and uniform surface finish
Improved mechanical consistency
Depending on forming complexity, different grades are selected.
Material Grades Explained

DC01 (EN 10130)
European equivalent of SPCC
General forming quality
Cost-effective and versatile
ST12 (DIN – old designation)
German traditional grade
Equivalent to DC01
Still commonly referenced in international trade
DC04 (EN 10130)
Deep drawing quality cold rolled steel
Lower carbon and higher ductility
Suitable for complex forming
DDQ (Deep Drawing Quality)
General term for steels optimized for deep drawing
Includes grades like DC04 / SPCD / SPCE
Excellent stretchability and forming stability
Equivalent Grades Comparison
| Standard | Grade | Forming Level |
|---|---|---|
| JIS G 3141 | SPCC | General forming |
| EN 10130 | DC01 | General forming |
| DIN (old) | ST12 | General forming |
| EN 10130 | DC04 | Deep drawing |
| JIS G 3141 | SPCD / SPCE | Deep drawing |
| Industry Term | DDQ | Deep drawing quality |
Chemical Composition (Typical, Max %)
| Grade | C | Mn | P | S |
|---|---|---|---|---|
| SPCC / DC01 / ST12 | 0.12 | 0.60 | 0.045 | 0.045 |
| DC04 / DDQ | 0.08 | 0.50 | 0.025 | 0.025 |
Lower carbon and impurity levels result in better deep drawing performance.
Mechanical Properties (Typical)
| Grade | Yield Strength (MPa) | Elongation A80 (%) | Application Type |
|---|---|---|---|
| SPCC / DC01 / ST12 | ≤ 280 | ≥ 28 | General forming |
| DC04 / DDQ | ≤ 210 | ≥ 38 | Deep drawing |

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.
