In order to apply the hot-rolled hig-strength steel sheets to the suspension parts with aim of reducing the automotive weight, the effects of microstructures and additional elements on formability were investigated. It has revealed that the fine BI type bainite that is composed of carbide free bainitic ferrite lath and cementite aggregates is the best material in the combination of both stretchability and stretch-flangeability at the range of tensile strength 590 to 780 MPa. The effect of microstructure on the perforation corrosion resistance in the P and Cu bearing corrosion resistant high-strength steels and the contributions of welded portion and punched edge to fatigue properties of hot-rolled high-strength steel sheets were also investigated.
