Annealed spring steel

CS70 is the the most popular choice if material for the manufacture of springs that require forming or shaping. It benefits from the fact that it can be supplied below 180 vpn in the annealed condition which makes the forming process much easier. Once the part has been stamped, pressed or forged to shape it is then hardened and tempered to achieve it’s final hardness and spring properties.

CS70 is equivalent to AISI/ SAE 1070, Din CK67 and Euronorm EN10132 C67S
