DC06 Cold Rolled Steel Coil
DC06 belongs to the category of ultra-low carbon steels and is distinguished by its exceptional cold-forming performance. Its chemical composition is strictly controlled to guarantee the desired mechanical behavior. In most cases, DC06 contains no more than 0.01% carbon and up to 0.20% manganese, along with extremely low amounts of phosphorus and sulfur. This minimal alloying content plays a key role in delivering outstanding formability and excellent weldability.
The mechanical specifications of DC06 are equally well defined. The steel features a maximum yield strength of 120 MPa and a tensile strength ranging from 270 to 350 MPa. Furthermore, DC06 provides a minimum elongation of 40%, highlighting its suitability for demanding forming processes. Thanks to these characteristics, DC06 is widely used in the manufacturing of highly complex and precision-critical components that rely heavily on deep formability-such as automotive deep-drawn body panels and advanced parts for the household appliance industry.
The DIN EN 10130 standard also outlines strict tolerances for dimensions, shape and surface quality. These tolerances ensure stable and reliable product quality that meets user expectations across different applications. In addition, cold-rolled flat steel produced to this standard can be supplied in multiple surface grades-from matte finishes to high-gloss surfaces-to accommodate diverse performance and aesthetic requirements.

- Surface types
The surface quality of cold-rolled flat products is a key element covered by DIN EN 10130. The standard specifies several finish options-ranging from smooth to matte-to suit different end-use requirements. High surface quality is particularly important when the material is used for subsequent coating processes or applications with decorative purposes.
Surface type A
Minor imperfections are permitted, including pores, slight grooves, small pimples, fine scratches and slight discoloration, provided they do not negatively affect formability or the adhesion of surface coatings.
Surface type B
The superior side must be completely free of defects to the extent that it does not interfere with the uniform appearance of high-quality coatings or electrolytically applied finishes. The reverse side must meet at least the minimum requirements of surface type A.
Our company can also supply the following cold-rolled steel grades:
DC01 – Designed for basic forming processes such as bending, embossing, beading and standard drawing operations.
DC03 – Intended for more demanding forming applications, including deep drawing and more complex profiling.
DC04 – Suitable for applications requiring high levels of formability.
DC05 – A deep-drawing grade developed to meet very high forming requirements.
DC06 – A special deep-drawing grade engineered for the highest demands in cold forming.
DC07 – An ultra deep-drawing grade tailored for extreme and highly challenging forming operations.
