A process,which consists of heating hardened steel below the lower critical temperature,followed by cooling in air or at any desired rate,is known as tempering.
Spheroidizing is a heat treatment process which results in a structure consisting of globules or spheroids of carbide in matrix of ferrite.
Practically all steels,which have been heavily cold worked,are subjected to this treatment.The process consists of heating steel above the recrystallization temperature and cooling thereafter.
A medium that is used for quenching is known as quenchants.The most commonly quenchants are water,oil,salts,air,gases and aqueous solutions.
In this treatment,steel is heated to a temperature below the lower critical temperature,and is held at this temperature for sufficient time and then cooled.
The special heat treatment given to medium carbon,high carbon and low alloy steels wire rod is called patenting.The process consists of heating the material well above the austenizing temperature to ...
Partial annealing is also referred to as interstitial annealing or incomplete annealing.In this process,steel is heated between the lower critical temperature and the upper critical temperature.
