"Standard" spring steel is available in several levels of qualities. The C-Class spring steel (1.1200) is the standard wire type most commonly used by Roveron. The applications for wire and sheet metal are indicated in the table below, as well as the desired heat treatments to ensure the best spring in the desired conditions.
C75 (1.1248) is the most common "ordinary" steel that is used for leaf springs. However, in practice this type of material will very often tear under deflection. We therefore advise our clients to opt for stainless spring steel (1.4310).
