About CK45 bon Steel Round Bar
CK45 is a general purpose medium bon steel delivered in as-rolled condition. It can be further heat treated to achieve specific mechanical properties. The 0.45% bon content is not favorable for welding, but it can be welded with appropriate pre and post weld heat treatment. Surface hardness of 57~62 HRC can be achieved with case hardening to a depth of approximately 1mm. Used for most transmission and motor parts of medium strength, case hardened parts such as camshafts, gears, rocking levers, simple hand tools, various types of fasteners and fixtures, and machinery parts and components with medium stress.
