Tempering (metallurgy) - Wikipedia
However, steel is sometimes annealed through a process called normalizing, leaving the steel only partially softened. Tempering is sometimes used on normalized steels to further soften it, increasing the malleability and machinability for easier metalworking. Tempering may also be used on welded steel, to relieve some of the stresses and excess ...

The Importance of Normalizing - INDEECO
Jan 12, 2015 · Normalizing is a thermal process often associated with forgings. Why do we normalize? The following article answers just that question. Normalizing imparts both hardness and strength to iron and steel components. In addition, normalizing helps reduce internal stresses induced by such operations as forging, casting, machining, forming or welding.
Heat Treatment of Steels Hardening, Tempering, & More
Normalizing involves heating steel, and then keeping it at that temperature for a period of time, and then cooling it in air.
