Frequently, Steel and Stainless Steel components require induction hardening to provide optimum performance and long service. Induction hardening, using induction heating and quenching, provides an economical way to process shafts, gears, bearings, yokes, spindles, sprockets, wire, tube, pipe or other parts.
Automatic handling of components and fixtures holding parts for heating and quenching provide for high throughput operation and help produce uniform results, part after part. Induction hardening is by far the fastest means of achieving hardening, the speed of the process results in a minimum of distortion, no surface decarburization, fine grain microstructure, and the ability to precisely control hardness patterns. induction is the perfect solution for many hardening requirements.
Induction Case Hardening
Selective induction case hardening can enhance performance of parts by providing hybrid mechanical properties, hardness where needed on wear surfaces and ductility in the core to provide impact resistance.
The selective induction hardening heat treatment has the ability to specifically target and apply heat rapidly throughout the case hardened zone, resulting in selective induction case hardening of a part. This is ideal for parts that are highly stressed in operation and require a combination of mechanical properties, such as high yield strength, fatigue resistance, and resistance to wear at the same time. There are many readily induction hardenable steels available.
The precise hardness pattern can be controlled by appropriate adjustment of the Frequency used, power density the induction coil geometry, the location of the part in the coil, and the heating cycle. Once fixed, the hardness pattern is consistent from part to part. Rotation during heating assures a uniform case while the rate of feed and power level of the generator determine the case depth.

Induction Through Hardening
A heating process to increase the hardness and tensile strength of material. Depending on the material, a variety of quenchants from water, oil, or air can be used. Induction heating technology is effective for through hardening operations and helps speed the process over traditional oven hardening approaches that can result in excessive grain growth and inferior part performance.

Progressive Induction Hardening | Induction Scanning
Frequently, parts require surface hardening in selected areas to provide optimum performance and long service. Induction hardening, using progressive heating and quenching, provides and economical way to process shafts or other parts.
By progressively passing a steel shaft through a heating coil into a water quench, the outer skin can be heated, quenched, and hardened without affecting its core. When a completely uniform case is required it is often necessary to rotate the shaft. The coil and the associate water quench usually form one unit, as the position of the water quench with respect to the inductor is very important. The water supply is often fed through the coil itself, as illustrated. Controlled scanning of shafts through the induction coil and quench ring while rotating produces controlled case depths over adjustable lengths of the shafts, all in on automated cycle.
Control of the case depth depends upon the power input from the generator and the downward speed of the shaft through induction coil while the length of the hardened section is controlled by a pyrometer which is set to suit specifications. Once the desired case depth and hardness patterns are found by matching equipment parameters, these settings can be made consistent for a repeatable process across every part.
