摘要

Valve springs are one of the automobile engine components that require a very high degree of fatigue strength and heat resistance. With the recent trend toward lighter cars and smaller engines, oil tempered wire used for valve springs needs to be smaller in diameter and higher in strength. About 80 years ago, Sumitomo Electric Industries, Ltd. started the production of piano wire, and has since been working hard to develop new materials and techniques for manufacturing steel wire for valve springs. This paper describes the history of the development of high-strength steel wire and its future.
