Characteristics and scope of application
Spring steel silicon and manganese improve elastic strength and yield ratio, improve hardenability, anti-tempering stability and anti-relaxation stability, and have low overheat sensitivity, but have a greater tendency to decarburization , especially when the silicon and carbon content are high, carbon is prone to graphitization, making the steel brittle. Spring steel is used as vibration-absorbing leaf springs and coil springs, cylinder safety valve springs on automobiles, tractors and locomotives, and can also be used as heat-resistant springs used below ℃.
