A cold drawn, precision ground and polished shafting, seam free surface finish is first induction hardened to a case depth of 0.050" to 0.090" resulting in a surface hardness of approximately Rockwell C 50 minimum, thereby ensuring the properties of the bar. The extra hardness ensures superior wear resistance. The bars are hard chromed in the same manner as chrome plated shafting allowing the same advantages of corrosion and wear resistance, but with the induction hardening, the bars will give superior service.
