Induction Hardening

Ultimate Durability for Demanding Applications
In heavy-duty industries like mining, construction, and agriculture, hydraulic cylinder rods and shafts are subjected to extreme stress, impact, and wear. To ensure maximum lifespan and prevent costly failures, a standard shaft is often not enough. At AC Honed Tube, we provide a superior solution through our expert induction hardening service

What is Induction Hardening?

Induction hardening is a precise, high-speed heat treatment process that creates a hardened, wear-resistant "case" or skin on the surface of a steel shaft, while the inner core of the shaft remains ductile and tough.

The process uses a powerful, high-frequency electromagnetic field to rapidly heat the surface of the shaft to a specific temperature. Once heated, it is immediately quenched (rapidly cooled). This controlled thermal process alters the microstructure of the steel's surface, resulting in a significant increase in hardness and durability exactly where it's needed most—on the outside.

The Advantages of an Induction Hardened Shaft

• Superior Impact Resistance: The hardened outer case provides exceptional protection against dents, nicks, and damage from external impacts, which is a common cause of premature seal failure.

• Increased Wear Resistance: The high surface hardness dramatically reduces wear from friction and abrasive materials, extending the operational life of both the shaft and the hydraulic seals.

• Enhanced Fatigue Strength: The process increases the shaft's resistance to bending and torsional stresses, making it ideal for high-load applications.

• Tough Inner Core: Because only the surface is hardened, the shaft's core retains its ductility, allowing it to absorb shock and resist catastrophic failure under extreme loads.

Our Capabilities: Precision and Power

At AC Honed Tube, we have the specialised equipment and technical expertise to deliver precise and consistent results for your most critical components.

• We can induction harden shafts with diameters up to 240mm up to 14m.

This capability allows us to service a wide range of heavy industrial and mobile hydraulic equipment, ensuring your components are engineered for ultimate performance and reliability.
