What is a hard chrome bar?
Chrome-plated bars and tubes are primarily used as piston rods, a critical component in hydraulic cylinders.
Hard Chrome Bar For Cylinder
Hard Chrome Bars are meticulously produced through a process that involves the electroplating of a thin layer of chromium onto the surface of a metal bar, usually made of steel. This plating process not only protects the steel core from corrosion but also reduces friction, facilitating a smoother operation in mechanical systems. The bars come in various sizes and can be custom-made to meet specific requirements, offering flexibility in their application across different industries.

Product Features
Hard Chrome Bar Application
Hard chrome bar is a chromium-plated steel product used primarily as piston rod material in all standard applications in hydraulics and pneumatics. Common applications are found in cranes, dump trucks, lifters, garbage compactors, agricultural machinery and production equipment with movable sections.
Because hard chrome bar is normally used in conditions of high stress, friction and harsh climatic environment, the quality of the base metal and surface treatment are of paramount importance. Wear, impact and corrosion resistance, as well as high yield strength, surface smoothness and uniform quality are most important properties of hard chrome bar.
The basic grades of steel used in the manufacture are 1045, 4140 hardened and tempered and 1045 induction hardened.
Grade 1045 steel bar is primarily used in hard chrome bar manufacture due to its wide range of properties consistent with end use applications.
Grade 4140 is used in applications where greater yield strength is required and induction hardened grade 1045 is used in applications requiring greater surface impact resistance.
Packaging & Delivery
All sells honed tubes and chrome rods, usually shipped by sea. In this way, the shipping packaging of the honed tube and chrome rod should pay attention to rust, moisture and impact resistance.Before shipment, we use anti-rust oil with better salt spray resistance, or choose oil-free anti-rust packaging, such as anti-rust film and anti-rust paper.
The packaging of the chrome rod needs to avoid damage during transportation. Paper tubes and straw ropes are usually used for packaging to ensure the neatness of the piston rod and stored in the warehouse.
After all honed tube and piston rod products are packaged, they are packed into custom wooden boxes and transported to the freight port for loading into containers.
JNM GROUP is a quality-centered company. We implement various quality processes in the process of manufacturing honing tubes and piston rods to ensure that the products delivered to customers are of high quality. Adhering to the tenet of "integrity, gratitude, cooperation", "customer satisfaction, win-win cooperation", through continuous innovation and pragmatic management, our company has formed a stable market foundation and a good industry reputation. Our products are deeply loved by customers in Southeast Asia, the Middle East, Central and South America, Europe and other countries.
