The piston-rod material 20MnV6 hard chrome plated with the material number 1.5217 is suitable for universal use and is very tough and corrosion-resistant.
Hard chrome plating means that an especially thick chrome layer is applied between pre-honing and finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV.
Hard chrome plated piston rods can be used between -30 °C and 200 °C.
