What is normalizing in metalworking?
Normalizing is a heat treatment that heats steel above its critical temperature and air-cools it to produce a uniform, fine-grained microstructure. It relieves stress and improves machinability.

Annealing
Annealing is a heat treatment process that softens metal by heating it to a specific temperature and slowly cooling it. It relieves internal stress and improves ductility for forming.
Heat Treating(HT)
Heat treating is a group of industrial processes that alter the physical and mechanical properties of metal through controlled heating and cooling. It includes annealing, hardening, tempering, and normalizing.
Hardening and Tempering(H&T)
Hardening heats steel above its critical temperature and quenches it rapidly to increase hardness. Tempering then reheats it at a lower temperature to reduce brittleness while retaining strength.
