Performance Requirements for Snap Rings

by:Tronshal     2022-02-18
In recent years, combined with Chinese resources and according to the requirements of new technologies for automobile and tractor design, new steel grades with boron, niobium, molybdenum and other elements added to silicon-manganese steel have been developed, which prolongs the service life of the snap ring and improves the speed of the snap ring. Ring quality. The snap ring is mainly made of carbon spring steel, so its performance is also determined by the spring steel. Snap ring spring steel is used under impact, vibration or long-term alternating stress, so spring steel is required to have high tensile strength, elastic limit and high fatigue strength. In the process, the spring steel is required to have a certain hardenability, not easy to decarburize, and good surface quality. Carbon spring steel is high-quality carbon structural steel with a carbon content of WC in the range of 0.6%-0.9%. Alloy spring steels are mainly silicon-manganese steels, their carbon content is slightly lower, and their performance is mainly improved by increasing the silicon content Wsi; in addition, there are alloy spring steels of tungsten, tungsten and vanadium.
