Hydraulic cylinder piston rod with induction hardening treatments

Market standards treated bars may guaranty a surface resistance up to 55 HRC, but no guaranty on the hardness below this surface.Specific production facilities in THS enable us to provide a hardness of 55HRC not only at surface of the piston rod, but also between 2 and 3 mm of depth.

Hydraulic cylinder piston rod coating treatment:

Coating treatments on piston rods, like chromium or nickel chromium, have a major influence on the lifetime of the hydraulic cylinders, based on the various constraints it is exposed to in its environment.

During co-development step of the cylinders, based on the conditions of use and stresses to be exposed to, our Engineering department will propose you the best cost-to-design solutions. 

-best material 

-type of welding used 

-treatment to be applied

-proper coating for piston rod

The quality of the chrome plating is vital to ensure proper coefficient of friction for seals, scratch resistance and corrosion resistance.
