The normalizing process is generally applied to unalloyed steels or low-alloy (hypoeutectoid) steels (i.e., steels with a carbon content lower than 0.77%). Normalizing is applied to hypereutectoid steels (i.e., steels with a carbon content greater 0.77%) only in special cases.

Forging is a not only an ancient craft, it is a science in the manipulation of steel into a predetermined shape that is roughly the final shape of the component to be manufactured.
