Spring steel


Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.

Grades

Many grades of steel can be hardened and tempered to suit application as a spring; however, some steels exhibit more desirable characteristics for spring applications.
