DIN 17222 Ck55 1.1203 Cold Rolled Steel Strips for Springs

 

Cold rolled steel strip for springs is distinguished by high dimensional accuracy and good surface quality and, in the cold rolled + hardened + tempered condition (H + A) offers the possibility of achieving high values of hardness, tensile strength and elastic limit.

 

Ck55 1.1203 Introduce

Ck55 steel has a higher (0.55%) carbon content for greater strength than the lower carbon alloys. It is hardenable by heat treatment, quench and tempering.
