In normalizing, the steel part is heated into the austenitic region followed
by cooling in air. Normalizing produces a more uniform microstructure and improves strength
and hardness. Benefits of annealing include increased ductility, grain refinement, better
machinability, dimensional stability, and improved response to subsequent hardening heat
treatment.
NATIONAL HEAT TREAT can perform normalizing in any of our five(5) atmosphere furnaces.
