Spring steel refers to special steel grades for manufacturing various springs and other elastic components. Springs mainly include leaf springs, coil springs and other elastic elements. The main function is to absorb impact energy and ease mechanical vibration and impact.
Spring steel is divided into non-alloy spring steel (ie carbon spring steel) and alloy spring steel. Alloy spring steel: generally contains 0.45%~0.70% carbon and a certain amount of alloying elements such as Si, Mn, Cr, V, W and B. The addition of alloying elements improves the anti-relaxation properties of the spring steel and improves the toughness of the steel. Carbon spring steel: The steel contains 0.60%~0.90% carbon and 0.3%~1.20% manganese, no other alloying elements are added, and the cost is low.
