Carbon Steel 1020

1020 steel (1.0330 material) is a cold formed European standard cold rolled high-quality low-carbon steel plate. In BS and DIN EN 10130 standards, it includes five other steel types: DC03 (1.0347), DC04 (1.0338), DC05 (1.0312), DC06 (1.0873) and DC07 (1.0898). The surface quality is divided into two types: DC01-A and DC01-B.
DC01-A: Defects that do not affect the formability or surface coating are allowed, such as air holes, slight dents, small marks, slight scratches and slight coloring.
DC01-B: The better surface shall be free of defects that may affect the uniform appearance of high-quality paint or electrolytic coating. The other surface shall meet at least surface quality A.
The main application fields of DC01 materials include: automobile industry, construction industry, electronic equipment and household appliances industry, decorative purposes, canned food, etc.
