Comparative Analysis of Induction and Furnace Tempering

Dec 02, 2016 · For the induction tempering procedure, the thermal data was measured by both a thermocouple and a thermal camera that was connected to computer-recorded data. The measurement results are shown in Figure 1. The furnace tempering experiments only include the heating process, and the induction tempering experiments include heating and cooling GH INDUCTION Induction Hardening and tempering Tempering is a process able to decrease the hardness, strength and increases the toughness of hardened steels, while removes the tensions created in the temple, leaving the steel with the required hardness.

INDUCTION HEAT TREATING STEEL:A Guide to the Heat

Induction Heat Treating Tempering While hardened steel is very strong, uneven cooling can cause microscopic stresses. Reheating the steel, known as Tempering, can correct these micro stresses and results in a more durable material. While the hardness of the material is reduced somewhat, the material is more durable as it is less brittle. Induction HARDENING AND TEMPERING OF TOOLS Tempering involves reheating the hardened tool/die to a temperature between 150-675°C, depending on the steel type. A process which controls final properties whilst relieving stresses after hardening, tempering can be complex; some steels must be subjected to multiple tempering operations.
