Chrome plated rod is known as chrome plated bar or chrome plated shaft also, they are the same product. They are called chrome bar, chrome rod or chrome shaft for short sometimes.
Hard chrome plated bar is a chromium-plated round steel product used primarily as piston rod material in all standard applications in hydraulics and pneumatics. Popular applications are found in dump trucks, lifters, garbage compactors, cranes, agricultural machinery and production equipment with movable parts. Chrome plated bars & rods are mostly used as piston rods (cylinder rods), which is a critical component in hydraulic cylinders and pneumatic cylinders. The basic function of transforming hydraulic power to a linear motion whilst preventing ingress of abrasive media into the hydraulic system will stipulate a set of demands on the rod.
As the chrome plated rod/ bar is usually used as hydraulic cylinder shafts, pneumatic cylinder shafts and other machine shafts, so they are known as Hard Chrome Plated Shafts also.
This product is mostly produced from round carbon steel rods, by using high precision centerless grinding and polishing methods, and then chrome plated to a certain plating thickness such as min. 20 microns (0.0008″), min. 25 microns (0.001″), min. 50μm (0.002″) and so on.

Our factory’s chrome plated bars are oiled with anti-rust oil on the outer diameter surface, then each chromed rod is protected with a cardboard sleeve (paper tube), and then packed in wooden cases. Please refer to below photos.
Induction hardening of piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them.
As the first level chrome plated rod manufacturer, our factory has been manufacturing & supplying Induction Hardened Chrome Plated Rods /bars/shafts for more than 25 years, our hard chrome plated rod and Induction Hardened Chrome Plated Bar are widely used in hydraulic cylinders and pneumatic cylinders.
The Induction hardened chrome plated rod results in a superior impact resistant bar ideal for high quality piston rods capable of handling tough environments.
Different from the normal chrome plated rods, the induction hardened chrome plated rods are heat treated by induction hardening.
Induction hardened is a type of heat treatment process, for which a metal part is heated to a certain temperature by induction heating and then quenched.
Here below are the material specifications of the induction hardened chrome plated rods.
