Induction hardening is localized surface treatment to enhance the mechanical properties of ferrous components without altering the structure of the original core. This process is highly beneficial as it provides hard surfaces, resistant to wear, galling, fatigue and impact. In addition, it provides greater resistance to traction and torsion in transmission elements.

The induction tempering process is electromagnetic in nature and is based on the application of a variable electrical current through an inductor. This current generates heat in the ferrous part due to magnetic hysteresis losses and the Joule effect. Heating occurs only in the surface layer of the part until the austenitizing temperature is reached, which depends on several controllable parameters such as power, frequency, time, design, and inductor concentration. Once the structural transformation is completed, the part cools down quickly.

It is important to note that the design and manufacture of the inductors used in this process is in-house and forms part of the company’s know-how.

Induction tempering is used in a wide range of parts, from small automotive parts such as transmissions, wheel hubs, bearing rings, forks, axles, screws, and cams, up to large drawing dies such as foundation plate, studs and blades, among others.

The main fields of application of this process are automotive and industrial vehicles, where heat-treated parts are essential to ensure the durability and performance of the components. For the automotive sector we hold the IATF Certification. In addition, it is also applied in the capital goods and lifting sectors, where strength and reliability are required in the parts used.
