DC04 – Cold rolled steel
The mechanical properties of DC04 are characterized by a low yield strength of maximum 210 MPa and a tensile strength between 270 and 350 MPa. Particularly noteworthy is the high elongation at break of at least 38%, which illustrates the excellent formability of the material. These properties make DC04 a preferred choice for the production of complex components that require high precision and surface quality, such as car body components in the automotive industry or filigree parts in the electronics industry.
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 high-gloss, to meet the specific requirements of different applications.
The special deep-drawing grade DC04 is specified in accordance with the standard DIN EN 10130, which focuses on cold-rolled flat products made of soft steels for cold forming. This standard specifies the technical requirements and test methods for cold-rolled products that are important in numerous industrial applications, especially where high formability and excellent surface quality are required.
DC04 is a low-carbon steel that impresses with its exceptional cold formability. The chemical composition of DC04 is precisely balanced to ensure that the material has the desired mechanical properties. The carbon content in DC04 is typically a maximum of 0.08 %, while the manganese content is a maximum of 0.40 %. This composition supports the high formability and weldability of the steel, making it ideal for demanding forming processes.
