  • As with chrome plated shafting, the basic material is cold drawn, precision ground and polished AISI 1045 shafting. It is first induction hardened which results in surface hardness of approx. Rockwell C 55.
  • This improves the properties of the bar and the extra hardness ensures superior wear resistance. The bars are then hard chrome plated in the same way as chrome plated shafting with the same advantages of corrosion and wear resistance. However, the induction hardened bar will give superior service
Typical Applications
  • Hydraulic shafting, oil and water pump shafting, rotary pump shafts, and piston rods
