In automotive body designing, high strength steels are applied in Order to achieve weight reduction and high crashworthiness. 980 MPa class ultra-high strength steel is recently applied to seat parts. However, it has less, formability than that of conventional high strength steels. To meet this demand, three types of 980MPa ultra-high strength steels are developed, which are good elongation type, high stretch .flangeability (high hole-expandability) type and balanced type.
