Is DC07 a Superior Alternative to DC05 for Ultra-Deep Drawing Applications?

Both DC05 and DC07 belong to the high-formability group of EN 10130 cold rolled steels. DC05 is an extra-deep-drawing steel widely used in automotive and electrical appliance components requiring good ductility. However, DC07 goes a step further, offering even lower yield strength and greater elongation, making it the top-performing grade for extremely demanding shapes.

Comparison of Forming Capabilities

Although DC05 supports excellent deep drawing, DC07 is specifically engineered for maximum deformation resistance—ideal for extreme geometries where even DC05 may fail.

Performance Benefits of DC07 Over DC05

Highest Level of Drawability
DC07 delivers the maximum elongation available in EN 10130 steels.

Improved Dimensional Stability
Better control of anisotropy reduces the risk of earing and uneven wall thickness.

Supports Extremely Thin Components
DC07 can be processed into thin-gauge sheets and coils while maintaining structural consistency.

For the most demanding forming tasks, DC07 clearly outperforms DC05.
