What is induction hardening?

Induction hardening uses induction heating and rapid cooling (quenching) to increase the hardness and durability of steel. Induction is a non-contact process that produces intense, localized and controlled heat quickly. By induction, only the part to be hardened is heated. Optimal results are achieved by optimizing the heating cycle, frequency, and process parameters such as coil and quench design. 

What are the advantages of induction hardening?

Induction hardening increases throughput. It is a very fast and repeatable process that can be easily integrated into a production line. It is clean, safe and usually has a small footprint. Workpieces are usually treated individually. This ensures that each individual workpiece is hardened to its own exact specifications. The optimized process parameters for each part can be stored on your server. Induction hardening is very energy efficient because only the part to be hardened is heated. 

Where is induction hardening used?

Induction is used to harden many parts. Examples include: gears, crankshafts, camshafts, drive shafts, output shafts, torsion bars, rocker arms, isokinetic universal joints, tulips, valves, rock drills, slewing bearings, inner and outer rings.

Induction hardening and tempering

Induction technology is most commonly used for quenching and tempering procedures, and it offers the most obvious advantages. The process requires a very high degree of precision in heating and quenching the steel to achieve the desired hardness distribution. Even very small variations in the process, such as excessive heating times or quenching at the wrong temperature, can lead to large differences between parts. Therefore, precise control of the process becomes essential. Induction technology offers more control than any other heating method.

Automated handling and fixing of components for heating and hardening provides high productivity and helps produce consistent results after the part. Induction is by far the fastest method of hardening and heat treatment. As a result, the process produces minimal distortion, no surface decarburization, fine grain microstructure and precisely controlled hardness patterns. Induction is the perfect solution for any facility looking to take production to the next level.
