Specification :

Hard Chrome Plated Steel Bars are designed to meet your specific needs for piston rod material in Hydraulic and Pneumatic Cylinders and other applications. Most advanced techniques of surface removal, polishing and hard chrome plating are used in manufacturing the above bars.

These hard chrome plated bars being available in standard sizes, chemistries and plating thickness, have convinced many design engineers to put Vardhman Steel Bars to work in construction, material - handling equipment, farm equipment, industrial machinery and almost anywhere, where precision, top quality Piston rods are required. These bars being preprocessed materials, you can save processing, time, energy, money and eliminate multiple vendor tensions. When delivered to you, no processing steps turning, grinding, finishing and plating are required.
