CR6, also known as ultra deep-drawing grade, is the highest grade of cold-rolled steel in accordance with the VDA 239-100 standard. This specially developed steel offers maximum formability and an extremely low yield strength, making it ideal for the most complex shapes and deep drawing processes. CR6 is the optimum solution for the most demanding applications in the automotive and manufacturing industries where maximum precision and freedom from deformation are required.

Material properties and composition
The exceptional properties of CR6 are based on an optimized chemical composition and an innovative production process:

Thanks to these properties, CR6 is designed for the most extreme requirements in forming technology and outperforms all other cold-rolled steels in the category of deep-drawing grades.

Applications
CR6 is used in a wide range of industries where the deepest drawing processes and most complex geometries are required. Typical applications include:

Advantages compared to other grades
CR6 clearly sets itself apart from other cold-rolled deep-drawing grades such as CR4 and CR5 by offering maximum formability combined with outstanding surface quality and dimensional accuracy. CR6 demonstrates its outstanding properties particularly in multi-stage forming processes that require deep drawing operations and precise details.

Conclusion
CR6 (ultra deep-drawing grade) in accordance with VDA 239-100 sets new standards in forming technology. Thanks to its exceptional formability, stability and dimensional accuracy, CR6 meets the highest demands of manufacturers who require the most complex geometries and maximum precision. Whether in the automotive industry, medical technology or the production of electronic components – CR6 is the top choice for innovations in demanding forming processes.
