Frequently, steel and stainless steel components require hardening to provide optimum performance and lifespan. Radyne Induction hardening equipment provides an economical way to process shafts, gears, bearings, yokes, spindles, sprockets, wire, tube, pipe, and many other parts.
Automatic handling and fixturing of components for heating and quenching provides for high production rates and helps to produce consistent results part after part. Induction is by far the fastest method of hardening and heat treating. 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 step up production to the next level.
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.
Selective induction hardening has the ability to specifically target and apply heat rapidly to a localized area of a part. As a result, the part develops a layer, or case, of hardened material around the outside of that area. This is ideal for parts that are highly stressed in operation and require a combination of mechanical properties. For example, high yield strength, fatigue resistance, and resistance to wear at the same time.
The precise hardness pattern can be controlled by appropriate adjustment of the frequency used, induction coil geometry, power level, and the location of the part in the coil. The hardness pattern remains highly consistent from part to part due to industry leading precision in Radyne systems. Rotation during heating assures a uniform case.

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.
Radyne’s Conveyorized Hardening Line is a great solution for high volume production of many parts including axes, hammers, and other types of hardened products.
Radyne’s Fastener Systems deliver up to 600ppm with precision heating and quenching with ease-of-use and industry leading reliability. Radyne’s Fastener Heat Treating equipment delivers uniformity, consistency and offers increased controllability that results in superior quality fasteners.
Radyne provides many small modular heat treating system components from scanners through to rotary indexor and pick and place based handling systems. Each is custom tailored to the needs of specific components and production environments.
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.
The ScanMaster™ is a high performance induction scanning system able to accommodate heat treating for a wide variety of part weights and lengths.
