摘要

Hot-dip galvannealed steels of 780MPa and 980MPa grades have been developed which exhibit low yield point (YP) and excellent formability. These steels are being increasingly incorporated in automotive bodies to improve fuel economy through body weight reduction. These newly developed 780MPa and 980MPa grade steels also exhibit higher spot-welded joint strengths. Crash tests show that these newly developed steels can effectively absorb more energy both for axial-crash and bending-crash conditions compared to conventional steels. These results indicate that the newly developed steels can replace conventional low strength steels currently used for automotive bodies.
