Process performance
The spring is used under impact, vibration or long-term cross stress, so spring steel is required to have high tensile strength, elastic limit, and high fatigue strength. Alloy spring steel is mainly silico-manganese steel, their carbon content is slightly lower, mainly by increasing the silicon content Wsi to improve performance; there are also chromium, tungsten, vanadium alloy spring steel. In recent years, combining Chinese resources and in accordance with the requirements of new technologies for automobile and tractor design, new steel grades with elements such as boron, niobium, and molybdenum added to the silicon-manganese steel have been developed to extend the service life of the spring and improve the quality of the spring. .
