How it works
STEP 2Parts are heated to a specific temperature to provide the required final hardness (temper).
STEP 3Parts are removed from the furnace to continue to subsequent processing such as cleaning and inspection.
Tempering, sometimes called Drawing, is the process of re-heating hardened steels to reduce hardness and increase toughness. The tempering temperature depends upon the desired properties and the purpose for which the steel is to be used. Increasing the tempering temperature will reduce the hardness of the steel while increasing the toughness.
