Description of Tempering Furnace

Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.

Tempering Furnaces are batch type units equipped with recirculating fan(s) and gas-fired or electric heating systems. Tempering Furnaces are designed for tempering or stress relieving in air, nitrogen, argon or hydrogen atmospheres. Tempering Furnaces are used for a variety of heat treating applications including those requiring inert atmospheres.
