What is 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.
There is a category of steel known as cold-rolled and hot-rolled. With cold rolled steel, the metal is subjected to an additional formative process after it has been hot rolled to make it more precise in dimensions, surface finish, and mechanical properties. While hot-rolled steel is formed at elevated temperatures, cold-rolled steel is not. Instead, cold rolling is achieved at ambient temperatures and any such deformation is done at room temperature. In this method, thinner sheets or strips are passed through pairs of rollers to compress and impose the tissue, causing stricter tolerance levels and some decent improvement in surface textures.

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
