The Hardness Of Ck45 induction hardened Chrome Rod

 Induction hardening is a non-contact process used for the surface hardening of steel and other alloys. The parts to be treated are placed inside a copper coil and heated above their transformation temperature by applying an alternating current to the coil. The cylinder rod is then quenched to retain the enhanced properties of the steel alloy. During this process, the induction hardened chrome rod core remains unaffected and its physical properties remain the same.

CK45 is a medium tensile carbon steel supplied in the turned, induction hardened and straightened, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 670 Mpa, an induction hardened case of 3.2mm thick approx. to Rc55-65, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, supported by an induction hardened case offering greater strength and resistance to mechanical damage, coupled with good core strength.

CK45 induction hardened chrome rod is used extensively by the hydraulic and pneumatic industries, for those applications utilising its high surface hardness and excellent resistance to surface impact.
