DC01 steel
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.
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 Technical Specifications
1. Chemical Composition
| Element | Max Content (%) |
|---|---|
| Carbon | ≤0.12 |
| Manganese | ≤0.60 |
| Phosphorus | ≤0.045 |
| Sulfur | ≤0.045 |
| Nitrogen | ≤0.009 |
2. Mechanical Performance
| Property | DC01 |
|---|---|
| Yield Strength | 140–280 MPa |
| Tensile Strength | 270–410 MPa |
| Elongation | ≥28% |
| Hardness | ≤60 HRB |
These mechanical characteristics ensure DC01 can be used for general forming, bending, profiling, and moderate stamping applications.
Advantages of DC01 for Industrial Applications
1. Stable Formability
Ideal for processes such as rolling, bending, stamping, and punching.
2. Consistent Surface Quality
Essential for visible parts, coated surfaces, and precision assemblies.
3. Excellent Coating Suitability
DC01 is widely used in powder coating, galvanizing, and electrostatic painting.
4. Competitive Cost Structure
It provides an economical balance between mechanical strength and formability.
