抄録

The paper reviews Nippon Steel's research and development systems and describes its approach to dealing with the requirements of the automobile industry for high strength steel sheets in terms of steel properties, such as, formability, weldability, paintability and corrosion resistance.
The paper also explains the corporation's technologies for the production of hot-rolled, cold-rolled and surface treated high strength steel sheets and the properties of these products.
For the trends of the expanding applications of high strength steel sheets and the growing demand for higher strength steel, the paper emphasizes the necessity for overall measures to promote technical improvements in both the manufacture and the fabrication of high strength steel sheets.
