DC03 – Cold rolled steel
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.
The mechanical properties of DC03 are also clearly defined. The material has a yield strength of at least 140 MPa and a tensile strength of between 270 and 370 MPa. In addition, DC03 has an elongation at break of at least 34%, which underlines its excellent formability. These properties make DC03 particularly suitable for the production of complex components that require high precision and surface quality, such as body parts in the automotive industry or household appliances.
The DIN EN 10130 standard also specifies the tolerances for dimensions, shape and surface finish. These tolerances are crucial to ensure consistently high product quality and to meet the requirements of end users. The surface of the cold-rolled flat products can be supplied in various qualities, from matt to glossy, to meet the specific requirements of different applications.
