DIN 17222 Ck67 1.1231 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.

 

Ck67 1.1231 Introduce

Ck67 1.1231 steel is an unalloyed medium carbon engineering steel which has 0.65%-0.72% Carbon. Ck67 steel with low hardening capacity designed for less loaded springs, periodically working for oil hardening
