Induction heat treating is a widely used process for the surface hardening or selective hardening of steel. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The core of the component remains unaffected by the treatment and its physical properties are those of the bar from which it was machined, while the hardness of the case can be much higher, depending on the hardenability of the particular steel. Carbon and alloy steels with a carbon content in the range 0.40/0.45% are most suitable for this process.
Dual scanners, indexers and single shot RF units allow us to offer a wide array of induction hardening capabilities to meet your localized heat treating needs. Part sizes can range from the smallest rivet to a large gear or shaft, up to 54” long. Since these components play important roles in many equipment functions in the automotive industry, they require highly sensitive handling and processing. This careful handling prevents damage to parts, including nicks, dents, and cracks, for the duration of the induction heat treating process.
