Structural steel spring-spring. To achieve higher performance characteristics, steels alloyed with silicon, chromium and vanadium are used. A characteristic feature of such steels is the presence of carbon in them from 0.5% to 0.8%. These steels have a high yield strength, which provides high elastic properties. This is achieved by quenching, followed by an average vacation.
