The influence of the chemical composition, including harmful and undesirable impurities, on the properties of spring steels

Abstrak

The role of various alloying elements in improving the mechanical properties of steels used for the manufacture of springs and springs is considered. The influence of carbon, silicon, manganese, chromium, nickel and vanadium on the elasticity, strength and resistance to relaxation of spring steels is investigated. The correct selection of alloying elements and heat treatment makes it possible to increase the yield strength and elasticity, resistance to small plastic deformations and wear resistance of steels. Special attention is paid to the role of silicon, manganese and vanadium, which, along with other elements, contribute to improving hardenability, prevent decarburization and provide resistance to cracking during deformation.
