A Cold Rolled Steel Sheet is hot-rolled steel further processed at room temperature for a smoother finish, precise dimensions, and increased strength, making it ideal for automotive parts, appliances, and furnitures, valued for its appearance and formability. This extra processing, which includes rolling below the recrystallization temperature, enhances hardness and yields a clean, uniform surface perfect for painting or coating,
EN 10130 DC01 Steel 1.0330 cold rolled steel sheet coil
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.
Cold Rolled Steel Sheet Grade DC01 Meaning and Definition
