    High quality

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 steel chemical composition is listed in the following table based on ladle analysis.

    • Yield strength: When the thickness is ≤0.7 mm but >0.5 mm, the yield strength value should be increased by 20 MPa. For thicknesses ≤0.5 mm, the value should be increased by 40 MPa.
    • Elongation: When the thickness is ≤0.7 mm but >0.5 mm, the minimum value of elongation should be reduced by 2 units. For thicknesses ≤0.5 mm, the minimum value shall be reduced by 4 units.
