This range of non-alloyed mild steels is designed for deep and extra-deep drawing applications. These products are used extensively in the automotive industry, for both visible and structural parts. The guaranteed low scatter in their mechanical properties ensures optimum productivity in drawing press operations.
The range of cold-rolled steels has been extended to include the ultra high-drawability CR6 grade, ensuring maximum efficiency in forming the most difficult parts (body sides, door liners, tailgates, etc.).
These high formability steel grades are non-ageing, conserving their mechanical properties and their formability over time.
The high formability steel range offers better guarantees than the usual standard-compliant drawing steels, while remaining compatible with these standards.
These steels are designed for deep and extra deep drawing of visible and structural parts.
Door lining in CR3-GI Extragal® (thickness: 0.7 mm)
Load compartment floor in CR3-GI Extragal® (thickness: 0.7 mm)
Wheel arch in CR5-GI Extragal® (thickness: 0.9 mm)
Crankcase in CR5-GI Extragal® (thickness: 1 mm)
These cross-references are given for information only. These high-formability grades generally offer guarantees of tighter mechanical properties

The above tables (for information only) summarise the cross-references between the high-formability steel range, European standards and the VDA 239-100 standard.
These steels have enhanced drawability properties as a result of minimal scatter in their chemical composition and mechanical properties, ensuring consistent behaviour during secondary processing.

This family of steels has high and even very high drawability in all deformation modes (low yield strength and high ductility and normal strain ratio). They can be used to manufacture complex parts incorporating several functions, synonymous with cost savings.
Forming limit curves can be used to define the maximum strain without necking for different deformation paths.
Examples of forming limit curves calculated for CR2 to CR6 (thickness: 1.0 mm) (ArcelorMittal model for Europe)
Examples of forming limit curves calculated for CR2 to CR6 (thickness: 1.0 mm) (Keeler model for North America)
Due to their low alloy content, drawing steels can be readily welded by all conventional welding processes.
