Super Purchasing for Hot Rolled Steel Strip - EN 10130 DC01 Steel 1.0330 cold rolled steel flat sheet – Ruiyi Detail:
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

- 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.
