3- Heat Treating - Normalizing

Normalizing, like annealing, is also a process for making material softer but does not produce the uniform material properties of annealing. A material can be normalized by heating it to a specific temperature and then letting it cool to room temperature outside of the oven. This process is less expensive than annealing becasuse the oven can be used for something else while the part is cooling down on the outside. However keep in mind that cooling down in ambient air is a lot like quenching in a liquid bath and may produce like results. (see quench tempering)
