Spring steel performance requirements
Spring steels are used under impact, vibration or long-term stress, so spring steels are required to have high tensile strength, elastic limit, and high fatigue strength. In the process, the spring steel must have certain hardenability, it is not easy to decarburize, and the surface quality is good. The carbon spring steel is a high-quality carbon structural steel with a carbon content of WC in the range of 0.6%-0.9%. The alloy spring steels are mainly silicon-manganese steel grades. Their carbon content is slightly lower, mainly by increasing the silicon content Wsi to improve performance; in addition there are alloy spring steels of niobium, tungsten and vanadium. In recent years, combined with China's resources, and based on the requirements of new technologies for the design of automobiles and tractors, new types of steel, such as boron, antimony and molybdenum, have been developed on the basis of silicon-manganese steel, which has extended the service life of springs and improved the quality of springs. .
