Hardened Surface 20MnV6 Chrome Piston Rod Custom Diameter

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 -15°C and 200°C.
