A 2001 SAE paper et al. [1,2] compared the formability aspects of six different grades of galvanealed steel [IF (270E), C-Mn (440W-1), low C - high Mn (440W-2), HSLA440 (440R), HSLA590 (590R) and DP590 (590Y)]. This study has been expanded to evaluate five additional advanced galvanealed steel grades [Low yield type DP780 (780YL), High yield type DP780 (780YM), DP980 (980Y), TRIP590 (590T), and TRIP780 (780T)]. The study presents material properties, forming characteristics in several lab tests and spring back characteristics. The study provides the actual and relative performance of these eleven steels and conclusions on the advantages these grades provide in cost-effective and mass-effective solutions to the manufacturing and performance requirements of the automotive body.
