The ferrous metal is heated to the austenite phase, above the transformation range, and is subsequently cooled in still air at room temperature. The normalizing heat treatment balances the structural irregularities and makes the material soft for further working.What is normalizing in metals?
Normalizing involves heating a material to an elevated temperature and then allowing it to cool back to room temperature by exposing it to room temperature air after it is heated. This heating and slow cooling alters the microstructure of the metal which in turn reduces its hardness and increases its ductility. Why Is Normalizing Used?How do you normalize steel at room temperature?
How it Works The normalizing of steel (Fig. 2) is carried out by heating ap- proximately 100°F (38°F) above the upper critical temperature (Ac. 3 or Acm) followed by cooling in air to room temperature, or at no greater than one-bar pressure using nitrogen if the process is being run in a vacuum furnace.What is normalizing at Thermex metal treating?
Normalizing at Thermex Metal Treating is a ferritic heat treatment process that is used to make a iron based alloy steel more ductile and tough. This is achieved after the part (s) have been subjected to thermal hardening processes. Normalizing involves heating the steel to an elevated temperature, followed by slow cooling to room temperature.
