DIN EN 10130 DC01 Steel (1.0330 Material) Data Sheet
DC01 steel (1.0330 material) is a European standard cold-rolled quality low-carbon steel flat product for cold forming. In BS and DIN EN 10130 standard, it contains 5 other steel grades: DC03 (1.0347), DC04 (1.0338), DC05 (1.0312), DC06 ( 1.0873) and DC07 (1.0898), the surface quality is divided into 2 types: DC01-A and DC01-B. In addition, this steel is also used under electrogalvanizing conditions. The designation of the steel is DC01+ZE (or 1.0330+ZE), and the standard is EN 10152.
DC01 Meaning and Definition
D: (Drawing) flat products for cold forming
C: Cold rolled
DC01: Drawing quality
DC03: Deep drawing quality;
DC04, DC05: Special deepdrawing quality;
DC06: Extra deepdrawing quality;
DC07: Super deep drawing quality.
Examples of Steel Names
DC01-A: Allow defects that do not affect formability or surface coating, such as pores, slight dents, small marks, slight scratches, and slight coloring.
DC01-B: Better surfaces shall be free from defects that may affect the uniform appearance of high-quality paints or electrolytic coatings. The other surface should meet at least surface quality A.
DC01+ZE: Electrolytically zinc coated
DC01EK: Conventionally enamelled
DC01 Steel Chemical Composition (EN 10130)
The following is a typical chemical composition range for DC01 steel:
| C (Carbon) | ≤ 0.12 | Controls hardness and strength; low carbon ensures high ductility |
| Mn (Manganese) | ≤ 0.60 | Enhances strength and hardenability; improves surface finish |
| P (Phosphorus) | ≤ 0.045 | Increases strength slightly but can reduce toughness |
| S (Sulfur) | ≤ 0.045 | Improves machinability but can decrease ductility |
| Al (Aluminum) | ≤ 0.07 | Used for deoxidation; improves grain refinement and surface quality |
| Fe (Iron) | Balance | Base element of the steel matrix |
DC01 Steel Physical Properties
DC01 has stable and predictable physical properties.
| Density | ρ / g·cm⁻³ | 7.85 | Provides structural mass and rigidity, consistent with standard carbon steels |
| Melting Point | °C | ~1,460 | Typical melting temperature for mild steel grades |
| Thermal Conductivity | W/m·K | 54 | Ensures good heat dissipation, useful for applications exposed to temperature changes |
| Specific Heat Capacity | J/kg·K | 486 | Indicates the energy needed to raise temperature; moderate heat absorption rate |
| Electrical Resistivity | µΩ·m | 0.12 | Moderate conductivity, suitable for general fabrication processes |
| Thermal Expansion Coefficient | µm/m·°C | 11.7 | Reflects predictable expansion under heat, allowing dimensional accuracy in coatings and welding |
| Magnetic Properties | - | Ferromagnetic | Easily magnetized; important for electrical and mechanical assemblies |
DC01 Steel Equivalent Grades
| 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. |
