Piston rods are coated on the surface with a layer of chrome, which ensures perfect smoothness and minimal friction.
According to the conditions in which the piston rod will be used, it is possible to choose from several material variants:
20MnV6 - the most used material in an environment where there is no mechanical damage or surface corrosion
42CrMo4 surface induction hardened - use for highly mechanically stressed components and in areas where mechanical damage to the rod surface (eg. quarries, ...)
For use in corrosive environments (rain, snow, sea climate) stainless steel piston rod or rod with the above-mentioned Nikrom-coated materials can be used.
