The properties of springs depend considerably on the metallnrgical qtmlity of the steel. Melting on the base of directly reduced iron diminishes the content of admixtures in the steel. The present work concerns the mechanical properties and fracture resistance of steel 60S2G-PV melted with the use of directly reduced iron, and the operational properties of fabricated springs. It is shown that the use of steel with enhanced purity for the production of springs increases their crack resistance and static and dynamic strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
