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.
The 42CrMo4 alloy steel round bar, crafted from high-grade carbon steel, stands out in the industry for its exceptional strength and durability. This product is meticulously calibrated to ensure precise dimensions and superior performance, making it a preferred choice for engineering applications requiring high tensile strength and resistance to wear and tear.
Composed of a balanced chemical structure that includes chromium, molybdenum, and manganese, the 42CrMo4 round bar provides enhanced toughness and hardenability. The presence of chromium offers excellent corrosion resistance and increases the steel's ability to withstand high temperatures without losing its structural integrity. Molybdenum enhances the material's strength and helps in maintaining its strength at high temperatures, making it ideal for critical components in the automotive and aerospace industries.
The round bars are produced through a rigorous process that involves controlled heating and cooling to optimize the mechanical properties. This process ensures that each bar meets stringent industry standards for both chemical composition and mechanical performance. The surface of each bar is free from defects and has a smooth finish, which reduces the need for further processing and allows for immediate integration into various manufacturing processes.
These 42CrMo4 alloy steel round bars are versatile and widely used in the manufacture of gears, axles, shafts, and other machinery components where high strength and resistance to impact are required. They are also suitable for creating parts that must endure heavy loads and continue operating in harsh environments.
Each batch of 42CrMo4 alloy steel round bars is subject to rigorous testing, including ultrasonic tests, to ensure that there are no internal defects. The products are also certified to meet international standards such as ISO, SAE, and ASTM, providing further assurance of their quality and reliability.
For businesses seeking a reliable material that provides both performance and longevity, the 42CrMo4 alloy steel round bar is an excellent choice. Its balanced composition and superior processing not only meet but often exceed the demanding requirements of modern engineering applications.
