DIN 17222 Ck60 1.1221 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.

 

Ck60 1.1221 Introduce

Ck60 1.1221 Carbon Steel is a high-carbon steel of low hardenability; it may be used in the as-rolled, annealed, normalized or liquid-quenched-and-tempered condition, depending on the desired properties. It is normally hardened by austenitizing and quenching in oil; however, it may be quenched in water if precautions are taken to prevent cracking. Its many uses include springs.
