DC03 – Cold rolled steel
The deep drawing grade DC03 is specified according to the standard DIN EN 10130, which focuses on cold-rolled flat products made of soft steels for cold forming. This standard defines the technical requirements and test methods for cold-rolled products used in various industrial applications, particularly where high demands are placed on surface quality and mechanical properties.
DC03 is a low-carbon steel characterized by excellent cold formability. The chemical composition of DC03 is precisely defined to ensure that the material has the required mechanical properties. Typically, DC03 contains a maximum of 0.10% carbon, a maximum of 0.45% manganese and traces of phosphorus and sulphur. This small amount of alloying elements contributes to the good formability and weldability of the steel.

We are manufacturer of steel products. We have quality steel coils and sheets for sale. Except for GI coils and sheets, we also have GL, PPGI, PPGL, Corrugated sheet, etc. to choose from. The standard seaworthy package contains waterproof kraft paper and plastic film inside, and steel sheets outside, then bound with steel strips. To secure it during transportation, we use wood pallets. During the two decades, we have developed complete systems from pre-sales consulting to after-sales service. Welcome to contact us for more information!
