Soft steels for cold forming – optimal materials for precise and efficient forming processes

Hot-rolled mild steels for cold forming

Mild steels for cold forming – also known as cold-forming steels or deep-drawing steels – are the ideal choice for applications that require the highest dimensional accuracy, excellent surface quality, and outstanding formability.

Thanks to their fine-grained structure and consistent mechanical properties, sheets made from hot-rolled mild steel can be easily bent, drawn, and punched without the risk of cracks or distortions.

thyssenkrupp Steel supplies mild steels according to DIN EN 10111 (DD11 to DD14) and VDA 239-100 (HR2).

Typical applications of mild steels for cold-forming

Mild steels are widely used in a variety of cold-forming applications thanks to their versatility and reliability. Typical uses include body components such as doors, fenders, and panels, as well as numerous automotive parts like brackets and consoles. In mechanical engineering, mild steels are frequently employed for housings, containers, and covers. They are also ideally suited for the production of deep-drawn components in various technical systems, where precision and material consistency are essential.

Key advantages of mild steels

Mild steels offer a range of benefits that make them a preferred choice for industrial and automotive applications. Their excellent deep-drawing properties enable precise shaping without material failure, while the uniform sheet thickness and consistent material structure ensure predictable forming behavior. The high surface quality allows for superior finishing and coating results, and their outstanding processability ensures smooth performance in automated production lines.
