5 Types of Heat Treating and Their Purpose in Precision Machining. Normalizing is an annealing process for steel where it is heated 150-200°F higher than in annealing and held at the critical temperature long enough for the transformation to occur.Steel treated in this way must be air cooled.6 Major Difference between Annealing and Normalizing Normalizing is a heat treatment technique that tends to happen on alloys of iron to help achieve uniform grain size.The metal is heated to a temperature above the critical point and cool it slowly in the air.Cooling the heated metal in air help to attain the required grain size uniformly throughout the alloy.Annealing Steel Annealing Metal Specialty Steel TreatingWhen diving into more specific purposes,companies might want improved hardness,corrosion resistance,toughness,and ductility.Depending on the desired outcome of the steel or metal,companies will choose one of several treatment options,with the top two options being either annealing or normalizing.
