Induction hardening is a rapid, economical process for surface hardening pins, shafts, gears, slips, and specialty items that require localized hardening without distortion of the part.

Parts are passed through a wire coil carrying AC current, which induces localized surface heating. Depending on process parameters, the result is a hardened case of thin to moderate depth. No subsequent polishing or cleaning is necessary, making the process relatively economical.

Induction hardening is ideal for medium or high carbon steels and alloys. The process increases wear resistance and can increase the strength of highly stressed components. Since the surface heating does not affect the core, induction hardening imparts in a highly reproducible localized surface hardening, with very low part distortion and low scaling.

Thermex will induction harden your components to your exact specifications, or work with you to develop the specifications and process most suitable to your application. All induction hardening is carried out under an ISO 9001:2000 Registered Quality Management System. Process equipment is automatically controlled for a high level of reproducibility. Test coupons are run regularly to confirm process performance.
