Hard Chrome Bar

Costar’s hard chrome bars perform excellent surface grinding and plating technique for hydraulic cylinder application. The reliability of our hard chrome bars is increasing as we strictly supervise products’ accurate concentricity and high abrasive and corrosion resistance in order to maximize the life of hydraulic cylinders.

The AISI 1045 / S45C bars are treated with precision centerless grinding and hard chrome plating technique after cold drawn, hard and abrasion proof, and own high corrosion-resistance ability. The machining accuracy meets international standards.
