20MnV6 Chrome Plated Rod Induction and Hardened (HRC 50–62)

The 20MnV6 induction hardened chrome plated rod is engineered for operations that require high fatigue resistance and long-term durability. The rod is manufactured from micro-alloyed 20MnV6 steel, known for its excellent machinability, toughness, and controlled microstructure.
After precision centerless grinding, the rod undergoes induction hardening, achieving a surface hardness of HRC 50–62, while retaining a tough and flexible core—ideal for hydraulic piston movement under heavy load. The final layer of hard chrome plating provides superior corrosion resistance, low friction, and long service life.
