Chrome Plated Rods

Chrome Plated Rods are produced from medium carbon cold-finished or hot rolled steel bars usually in Steel 1045/1050 or 10v45 grades. The bars need to be polished, and chrome plated to a minimum thickness of 0.0005″, and 0.001″ per side. Chrome Plated Rods are specifically designed to be used for most piston rod applications in hydraulic cylinders.

 

Nikrom Rod

As some of customers’ machines working environment is highly corrosive conditions, which required very high corrosion resistance. HangZhou LD provides an option of Nikrom rod.
Due to the presence of natural micro cracks in the chromium layer, erosion may penetrate the coating. In corrosive environments or strictly safe applications, exposure to the risk of mechanical damage, oil film alone is not enough to protect in the field.

 

This is especially true if the piston rod remains elongated for a long time as the oil film dries out. By combining the chromium plating with the lower nickel layer. Nikrom can greatly improve the corrosion resistance regardless of the overall oil film protection state of the piston rod.

Nitrided-Treating Rods

Compared with chrome plated rods, Nitrided rods’ black colored surface finish is very hard, and the hardness can be above 55 HRC. The process of liquid nitriding begins with the cleaning and super-polishing of the material to a surface roughness of 6 to 10 Ra.

 

The improved corrosion resistance can reach the requirements of 500-1000 Hours by Salt Spray Testing (ASTM B117), the nitrided rods are normally sufficient to protect the shaft during its entire life. Nitrided rods are cost effective alternative way for longer time salt spray testing requirements.
