Spring steel

"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).

CrV 1.8159 EN 10277-5 / DIN 17221 17222 Carbon spring steel Same as carbon steel, but for thick wire.
C75 1.1248 EN 10132-4 / DIN 17222 Carbon spring steel Plate: standard non-stainless stamping steel.

Heat treatments to achieve optimal springs:


Material Type Coiling Operating Temperature Heat treatment after coiling
B-class Spring hardness Cold Up to 200°C 240°C for 1 hours + Air cooling (A.C.)
C-class Veerhard Cold Up to 200°C 240°C for 1 hours + Air cooling (A.C.)
