Heat Treating

The primary metallurgical advantages of induction hardening include increased wear resistance and improved fatigue strength. A shallow hardened case, ranging from 0.25 to 1.5mm (0.010 to 0.060 inch) provides a part with excellent wear resistance in applications involving light to moderate loads. For shallow case depths, heating to the desired depth can be obtained by use of induction heating equipment operating at frequencies ranging between 50 kHz and 400 kHz. Deeper hardened cases ranging between 3.2 to 12.7mm (1/8 to inch) provides substantially improved torsional and bending fatigue strength. Deeper desired patterns are achieved from 25 kHz down to 1 kHz.

The use of electromagnetic induction for hardening and tempering parts has been widely use throughout the heat treating industry for more than 75 years. Rapid heat times, repeatable control and inherent adaptability to in-line or stand-alone processing make it ideal for modern manufacturing facilities.
