Induction hardened chrome plated rod is a high-performance component engineered for demanding applications in hydraulic and pneumatic systems. The induction hardening process significantly enhances the surface hardness and wear resistance of the steel core, while the hard chrome plating provides an additional layer of protection against corrosion and abrasion. This combination results in a durable and long-lasting rod capable of withstanding high loads, frequent movement, and harsh operating environments.

Manufacturing Processes

Induction Hardening: This heat treatment uses high-frequency currents to selectively harden the surface of the induction hardened chrome plated rod. The result is a hard, wear-resistant outer layer (with high surface hardness) while maintaining a tough and ductile core that can absorb impact and resist bending.

Chrome Plating: Following hardening, a layer of hard chromium is electroplated onto the surface. This plating acts as a protective barrier against corrosion and further enhances wear resistance. It also contributes to an exceptionally smooth surface finish, which is crucial for reducing friction and seal wear.

Key Features

Exceptional Wear Resistance：Hardened surface (typically HRC 55-60), smooth finish (Ra 0.2-0.4 μm)，Withstands abrasive conditions, significantly extends component lifespan.

Superior Corrosion Protection: Dense chrome plating layer (commonly 20-50 μm),Protects against rust and corrosion in humid or chemically harsh environments

High Strength and Durability: Tough, ductile core with high yield strength (800-1000 MPa), hardened surface layer,Resists heavy loads, impacts, and buckling, ensuring structural integrity.

Increased Operational Efficiency: Ultra-smooth surface reduces friction, Lowers energy consumption in systems like hydraulics and reduces wear on seals.

Product Applications

1、In automotive engines, induction hardened chrome plated rods are used as piston rods. The hardness and wear resistance ensure that the piston moves efficiently within the cylinder.

2、 These induction hardened chrome plated rods are used in hydraulic cylinders of industrial machinery. They can operate under high pressure conditions, ensuring the proper functioning of the hydraulic systems.

3、These induction hardened rods in manufacturing equipment such as presses and lathes, the rods are used to transmit force and motion.
