Normalizing

Normalizing is the process of heating a ferrous alloy to at least 100-degreesF above the transformation range and then cooling the material in still air to a temperature lower than the transformation range. The process produces a recrystallization and refinement of the grain in the material that results in uniform hardness and structure. Many high strength components are normalized prior to the harden and temper process for the purpose of optimization of the mechanical properties.
