AISI 1045 Mild Carbon Steel Round Bar Hard Chrome Plated Steel Bar

CHROME PLATED ROD /CHROME PLATED BAR GENERAL INTRODUCTION

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:

• Chrome rod for hydraulic cylinders, this is the most popular application.
• Pneumatic cylinders / air cylinders (chrome plated piston rods/ chrome cylinder rod)
• 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 shaft, Transport machinery center shaft, etc.
• Ejector rods for injection molding machines
• Vibration absorbers and pistons for some industrial machinery.

Packing

Chrome plated rods are typically packaged with a protective film or coating to prevent surface damage. They are further wrapped in paper or plastic for added protection, and often shipped in wooden crates or sturdy cardboard boxes to safeguard against mechanical damage during transport.
