Tempering (metallurgy) Wikipedia
网页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. The exact temperature

Hardening and tempering Appropedia, the sustainability wiki
网页The tempering operation is very important and must be performed on every piece which is hardened. Tempering should be done just as soon as the quenched part is cool enough to be comfortably handled in the bare hands. Tempering temperatures may vary from 225 o F. to as high as 800 o F., but the usual temperature is 400-800 o F.
