Abstract
Application of ultra-high-strength steel sheets is one of the most important methods to achieve both weight reduction and crash safety of a vehicle. There is a trend to apply ultra-high-strength steel sheets to some parts in a vehicle body. However, formability and weldability of ultra-high-strength steel sheets are strictly limited. In this work, several types of steel sheets with tensile strength of 980 MPa have been developed. Their properties are introduced and shown to be suitable for some automotive applications.
