Tempering
Tempering is a term primarily applied to steels (plain carbon and alloy steels, stainless steels, and tool steels) and typically involves heating component parts to temperatures below their critical temperature and holding long enough to help improve the microstructure. Tempering is a post-quenching process, and depending on the hardenability of the steel, is sometimes required as soon as 15 minutes after parts are removed from the quench tank. Generally, tempering lowers strength and hardness, but increases ductility and toughness.
