DC01 Steel Equivalent Grades
DC01 steel complies with the EN 10130 standard for cold-rolled low-carbon steel flat products. The following is a comparison of equivalent DC01 steel grades in major global standards:
| EN (Europe) | DC01 (EN 10130) | Cold-rolled low-carbon steel for cold forming applications. |
| DIN (Germany) | 1.0330 (St12) | Widely used grade in general cold forming and stamping processes. |
| ASTM / SAE (USA) | A1008 CS Type B / SAE 1008 | Commercial quality cold-rolled carbon steel used in automotive and appliances. |
| JIS (Japan) | SPCC (JIS G3141) | Cold-rolled carbon steel sheet for general forming; similar mechanical behavior to DC01. |
| GB (China) | Q195 / Q215A | Mild carbon steel grades with good ductility and weldability. |
| ISO | CR1 | Low-carbon cold-rolled sheet metal suitable for forming operations. |
| KS (Korea) | SPCEN (KS D 3512) | Equivalent for deep drawing and pressing applications. |
What Is the Difference Between DC01 and DC03 Steel?
Both DC01 and DC03 fall under the EN 10130 standard for cold-rolled mild steel, with their main differences being in mechanical properties, formability and intended use.
| Designation | DC01 (EN 10130) | DC03 (EN 10130) | Both are cold-rolled low-carbon steels defined under the same standard. |
| Formability | Standard formability for general use | Improved deep-drawing capability | DC03 can handle more complex shapes without cracking. |
| Yield Strength (MPa) | 140–280 | 120–210 | DC03 has lower yield strength, allowing greater plastic deformation. |
| Tensile Strength (MPa) | 270–410 | 270–370 | Slightly lower tensile strength in DC03 enables better stretch and draw performance. |
| Elongation (%) | ≥28 | ≥34 | DC03 offers higher ductility for deeper draws. |
| Surface Quality | Good | Very good | DC03 has a smoother surface suitable for post-coating and painting. |
| Typical Applications | General sheet metal components, covers, brackets, enclosures | Automotive inner panels, appliance parts, deep-drawn housings | DC03 is preferred where complex shaping and surface appearance matter. |
| Cost | Lower | Slightly higher | The improved forming quality of DC03 comes at a modest cost premium. |

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.
