Abstract：SWRH82B high-grade spring steel wire is widely used in important engineering fields due to its high strength. This article studies the quality problems that occur during the deep drawing process of SWRH82B spring steel wire， analyzes the influencing factors， including surface quality， abnormal microstructure， etc.， and proposes improvement measures. The research results indicate that controlling the quality of raw material castings and controlling the formation of defects on the surface of raw materials are important ways to improve the drawing performance of SWRH82B steel wire.
