Induction and Hardened(HRC 50-62)

What is an Induction and Hardened Chromed Plated Rod (HRC 50-62)?

An Induction and Hardened Chromed Plated Rod (HRC 50-62) is a high-strength steel bar that has undergone induction hardening to achieve a surface hardness range of HRC 50-62.
The rod is then chrome plated, giving it excellent resistance against wear, pitting, and corrosion.
This combination makes it a preferred choice in hydraulic cylinder rods, pneumatic cylinders, and heavy-duty mechanical applications.
It is designed to withstand high stress, repeated impact, and long-term service without deformation.

What are the advantages of using Induction and Hardened Chromed Plated Rods?

These rods offer superior hardness and surface durability due to the induction hardening process.
The chrome plating layer provides anti-rust protection, extended lifespan, and a smoother sliding surface, reducing friction with seals.
They are capable of withstanding higher loads compared to standard normalized chrome rods, making them ideal for heavy-duty hydraulic systems.
Additionally, their dimensional stability ensures precise performance in demanding industrial environments.

Where are Induction and Hardened Chromed Plated Rods (HRC 50-62) commonly applied?

These rods are widely used in construction machinery, hydraulic presses, mining equipment, and industrial machines.
They are also suitable for telescopic cylinders, lifting systems, and mobile equipment where both strength and corrosion resistance are critical.
Because of their hardness and durability, they are preferred in environments with heavy wear and abrasive conditions.

How is the induction hardening process performed on chromed plated rods?

Induction hardening involves heating the surface layer of the steel rod using a high-frequency induction coil.
Once the surface reaches the desired temperature, it is rapidly quenched, forming a hardened martensitic structure.
This results in a tough, wear-resistant surface while maintaining a ductile and strong core.
After hardening, the rod undergoes precision grinding and chrome plating to achieve optimal surface finish and corrosion protection.

What is the difference between normalized chrome plated rods and induction hardened chromed plated rods?

Normalized chromed plated rods typically have a hardness range of HRC 15-22, making them suitable for standard hydraulic and pneumatic applications.
In contrast, induction hardened rods have a hardness of HRC 50-62, providing much greater wear resistance and strength.
While normalized rods are cost-effective for moderate-duty systems, induction hardened rods are the better choice for heavy-duty, high-impact, or abrasive working conditions.
