A special feature of CP-K® 780Y980T GI are the local forming properties typical of complex-phase steels – specifically: high hole expansion combined with outstanding bendability. With its comparatively high guaranteed yield strength of 780 MPa, which is 200 MPa higher than conventional dual-phase steels in this strength class, the new grade offers greater energy absorption, particularly in the case of lateral loads, and increased intrusion resistance.
The new body grade is supplied hot-dip galvanized and is available in thicknesses of 1.00 to 2.00 mm and widths of 1,000 to 1,450 mm. Its specific property profile makes it particularly suitable for parts with openings such as waistline reinforcements, but also for rockers and seat cross members with high strength requirements. A cold-rolled sheet grade intended particularly for use in interior seat applications will also follow shortly.
