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.
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
