Mainly because it has good elasticity, and because it works under dynamic load environmental conditions, the most important application for the material of spring steel is It has high yield strength and does not cause plastic deformation when bearing heavy loads. It should have high fatigue strength, long service life under repeated loads, and sufficient toughness and plasticity to prevent sudden brittle fracture under impact force. Spring is used under impact, vibration or long-term cross stress, so the spring steel is required to have high tensile strength, high elastic limit and fatigue strength. In terms of technology, spring steel is required to have a certain degree of hardenability, be difficult to decarburize, and have good surface quality. Carbon spring steel is a high-quality carbon structural steel with a carbon content within the range. Alloy spring steel is mainly silicon-manganese steel type. Their carbon content is slightly lower, and their performance is mainly improved by increasing the silicon content. There are also alloy spring steels of nickel, tungsten and vanadium. In recent years, combined with Chinese resources and in accordance with the requirements of new technologies in automobile and tractor design, new steel types have been developed based on silicon-manganese steel with boron, niobium, molybdenum and other elements added, which has extended the service life of springs and improved spring quality. .
Use of spring steel: Spring steel has high precision, good toughness, good wear resistance and stable quality.
The main spring steel type has a wide range of uses and can be used to manufacture various important springs of medium cross-section, such as automobile, tractor leaf springs, coil springs, etc. BB series has excellent hardenability, high tempering stability, decarburization and Low graphitization tendency, good comprehensive mechanical properties, certain corrosion resistance, and springs containing other elements have certain high temperature resistance. Since they are all high-grade high-quality steel, the fatigue performance is further improved. It is used to manufacture heavy-duty large sizes with large loads (~ ) important springs, such as engine valve springs, conventional weapon spring hook springs, spring heat-resistant springs, such as boiler safety valve springs, fuel injector springs, cylinder expansion rings, etc.
