Case Hardening: Solid vs Hollow Shafts

Induction surface (case) hardening of hollow shafts has unique features compared with hardening of solid shafts. With solid shafts, the core temperature typically does not rise significantly during heating. The […]

Intricacies of induction joining

Induction brazing different metals together using the same power supply may results in noticeably different depths of heating and heat intensity experienced by the different brazed components. This is due […]

Induction tempering vs oven tempering pt2.

The transformation to martensite through quenching creates a very hard and brittle structure. Un-tempered martensite is typically too brittle for commercial use and retains a large amount of internal residual […]

Coil failures pt 14: SPLIT-RETURN INDUCTORS

The main considerations when choosing an inductor style are the shape of the part, the desired heat-treat pattern, and the material handling to be used for production (i.e., how the […]

Coil Failures: Coils for Internal Surfaces pt. 12

In contrast to inductors used to heat external surfaces or outside diameters, the effectiveness of an internal coil depends to a much greater extent on the coil-to-workpiece gap. Electrical efficiency […]

Joining Components by Induction Brazing pt.1

Induction brazing and soldering have several advantages compared with heating the workpieces with flame. Since the joint is heated in a localized area in a short time, the rest of […]

Successful Induction Heating of RCS Billets

There are three basic induction approached to heat RCS billets: static, progressive and oscillating heating. The most popular of these is the progressive multi-stage horizontal heating system, in which billets […]

Crankshaft Hardening with SHarP-C

According to a patented non-rotational crankshaft hardening process, heat patterns are “locked in place” and very repeatable since neither the crankshaft nor the coils are moving. The same pattern is […]

Single Coil Dual Frequency: Gear Hardening pt. 2

True contour gear hardening pattern can be obtained utilizing this technology. Single-shot hardening of several powertrain components utilizing dual frequency systems dramatically minimizes distortion of induction hardened parts and provides […]
