The report discusses the recent development of spring steel in Japan during last 40 years. There has been a great increase in this steel production with the increase of production of automobiles. The technical trends of spring steel and springs are discussed in connection with hardenability, fatigue, high-stressed design and productivity. Especially, ways of improvement of performance of springs for suspention of automobiles were studied in respect to chemical composition, heat-treatment and manufacturing process.
