Induction Hardened Chromed Bar

The piston rod in a hydraulic cylinder is an important component that connects the hydraulic actuator to the machine component. It is typically made of cold-rolled steel and undergoes a process called hard chrome plating. The hard chrome plating involves applying a layer of chromium onto the surface of the rod through electroplating. This process provides several benefits, including increased hardness, improved wear resistance, and enhanced corrosion resistance.
The piston rod is highly ground and polished to ensure a smooth surface finish. This smooth finish helps to create a reliable seal between the rod and the cylinder, minimizing the risk of leakage and ensuring proper hydraulic functioning.
In some applications where there is a risk of external impact or damage to the piston rod, induction hardening is performed. Induction hardening is a heat treatment process that involves heating the metal part using induction heating and then rapidly quenching it.
