CR5, also known as super deep drawing grade, represents the highest quality level among deep drawing grades according to the VDA 239-100 standard. This steel was specially developed for applications that require particularly deep and complex forming processes. Thanks to its exceptional properties, CR5 is the first choice for high-precision formed parts and demanding production processes.

Properties and material composition
The outstanding performance of CR5 is based on its extremely low yield strength, high elongation and exceptional forming properties. These are achieved through a precise chemical composition and an optimized manufacturing route.

Areas of application
CR5 is used in industries where the deepest drawing processes and most complex geometries are required. Typical applications include:

Advantages compared to other grades
CR5 significantly surpasses the properties of CR3 (special deep-drawing grade) and CR4 (special drawing grade), especially when it comes to extreme forming requirements. Thanks to its even lower yield strength and outstanding ductility, CR5 is ideal for multi-stage deep drawing applications and components with extremely tight tolerances.

Conclusion
CR5 (super deep-drawing grade) in accordance with VDA 239-100 sets standards for demanding deep-drawing applications. Its exceptional formability, perfect surface quality and high dimensional accuracy make it the preferred choice for high-precision molded parts. Whether in the automotive industry, electronics production or in specialized areas such as medical technology – CR5 offers the optimum conditions for components with the highest quality requirements and geometric challenges.
