摘要

A large quantity of hot-rolled high-strength steel sheets have been used in automotive chassis parts to reduce weight. When thinner sheets are adopted for further weight reduction, their press formability and fatigue strength must be improved. This paper reports on the features of the TS 540-780 N/mm~2 grade hot-rolled high-strength steel sheet developed by Kawasaki Steel for improvement of the above characteristics, based on a new microstructural control method.
