Normalized(HRC 15-22)

What is a Normalized Chromed Plated Rod (HRC 15-22)?

A Normalized Chromed Plated Rod (HRC 15-22) refers to a steel bar that has undergone normalization heat treatment followed by chrome plating.
Normalization refines the grain structure of the steel, enhancing toughness and dimensional stability.
The chrome plating provides a hard, corrosion-resistant surface ideal for hydraulic cylinders, pneumatic actuators, and other precision applications.
With hardness in the range of HRC 15-22, these rods offer a balanced combination of strength, machinability, and wear resistance.

What are the advantages of Normalized Chromed Plated Rods compared to non-normalized rods?

Normalized chromed plated rods deliver improved toughness and fatigue resistance due to the normalization process.
They maintain dimensional stability during machining and welding, reducing risks of warping or stress-related failures.
Additionally, the chrome layer ensures excellent corrosion resistance, smoother surface finish, and extended service life, making them suitable for hydraulic piston rods, guide bars, and construction equipment parts.
Compared with non-normalized rods, they offer more reliable performance under dynamic loads.

What is the hardness range of Normalized Chromed Plated Rods?

The hardness range is typically HRC 15-22.
This range provides an optimal balance between flexibility and wear resistance.
The relatively moderate hardness makes the rod easier to machine or cut while still maintaining durability against friction and corrosion.
It is particularly advantageous in hydraulic systems where a certain level of ductility is required to withstand pressure variations.

What industries commonly use Normalized Chromed Plated Rods (HRC 15-22)?

These rods are widely used in the hydraulic and pneumatic industry.
They are essential components for hydraulic cylinder rods, pneumatic cylinder shafts, lifting equipment, agricultural machinery, and construction vehicles.
They are also applied in industrial automation systems, press machines, and heavy-duty mechanical devices where corrosion resistance and stable hardness are crucial.
The combination of normalization and chrome plating makes them suitable for both heavy-load and precision-engineered environments.

How do Normalized Chromed Plated Rods improve hydraulic cylinder performance?

In hydraulic cylinders, the piston rod must endure high pressure, constant friction, and exposure to harsh working conditions.
The normalized treatment ensures the rod has improved mechanical strength and toughness.
The chrome plating reduces friction, enhances sealing compatibility, and minimizes wear on seals, extending the cylinder’s service life.
This combination reduces maintenance frequency and ensures smooth, efficient operation in industrial and mobile hydraulic systems.

Are Normalized Chromed Plated Rods easy to machine and customize?

Yes, the hardness of HRC 15-22 provides a machinable structure without sacrificing durability.
They can be easily cut, threaded, or welded depending on the application.
Manufacturers often offer customization in terms of diameter, length (up to 15 meters), and surface finish quality.
This flexibility allows them to meet diverse application requirements, from standard hydraulic shafts to specialized mechanical parts.

What is the difference between Normalized Chromed Plated Rods and Induction Hardened Rods?

Normalized rods have a lower hardness range (HRC 15-22), making them more flexible and easier to machine.
Induction hardened rods, on the other hand, typically reach hardness levels above HRC 50, offering superior wear resistance but lower machinability.
Normalized chromed plated rods are ideal where moderate strength and corrosion resistance are sufficient, while induction hardened rods are used in heavy-duty, high-stress environments.
The choice depends on whether the application requires more toughness and machinability or extreme wear resistance.
