Chrome Plated Round Bars
Chrome plated round 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 rods 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:
- Hydraulic cylinders (chrome plated piston rods)
- Pneumatic cylinders / air cylinders (chrome plated piston rods)
- Guide rods for plastic manufacturing machine and hydraulic machinery
- Rollers for machines, such as packing machine rollers, printing machine rollers
- Shaft for machinery, such as Textile machinery center axle, Transport machinery center axle, etc.
- Ejector rods for injection molding machines
- Vibration absorbers and pistons for some industrial machinery.

1. Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
2. Chrome plating provides corrosion resistance along with an Extremely reflective look
3. High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely.
4. 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.
5. High performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi.

Steel 4140 is AISI standard grade, it is a kind of alloy structural steel, equivalent to China standard GB 42CrMo.
SAE 4140 alloy steel has high fatigue strength and low notch sensitivity, high low temperature impact toughness, no obvious temper brittleness, and is mainly used in the quenched and tempered state. It is used to manufacture high-strength parts and parts with large cross-sections and other stress-bearing components under impact load. Such as high strength Hydraulic cylinder rods, penaumatic cylinder rods, the transmission eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, etc.4140 chrome plated rod is manufactured through SAE 4140 steel bar, by using high precision centerless grinding and polishing methods, and then chrome plated to a min. plating thickness of 20 microns (0.0008″), 25 microns (0.001″), or other. The chrome plating layer provides corrosion resistance and a highly reflective appearance.
4140 chrome plated rods are used widely by the hydraulic industries and pneumatic industries, and is also widely usually used for applications where high yield strength and tensile strength is required.
