Chrome Plated Rod / Chrome plated bar is usually manufactured from cold rolled or hot rolled carbon steel roundbars, by using high precision centerless grinding and polishing methods, and then chrome plated to a min. platingthickness of 20 microns (which is 0.0008″). The chrome plating layer provides corrosion resistance and a highlyreflective appearance.
All the above providing us the ability to produce the best quality hydraulic cylinder rod (hydraulic cylinder shaft around.
Chrome plated rods are also known as hard chrome plated shafts, chrome steel bar, chrome plated shafting, and chrome rod for hydraulic cylinders.

WHAT IS THE ADVANTAGES OF OUR CHROME PLATED ROD?
Our factory's chrome rod for hydraulic cylinders is favored by customers because of the following advantages:
a. Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
b. Chrome plating provides corrosion resistance along with an Extremely reflective look
c. High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely.
d. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost.
e. High performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi, depends on the material and heat treatment method.
APPLICATIONS OF CHROME ROD
Chrome plated bar is mostly designed to be used for hydraulic piston rod and pneumatic piston rod manufacturing and repairing. So some people also may call this product hydraulic cylinder rod approximately.
However, besides the above, chrome plated rod can also be used in applications where high performance surface finishing and high accuracy dimension tolerance are required.
Here below is the application list of the chrome rods:
Here below are the main advantages of our products and services.
Introducing our top-of-the-line stainless steel round bars, tailored to meet the exact specifications of modern industries.
