Process Annealing: Process Annealing is used to treat workhardened parts made out of lowCarbon steels (< 0.25% Carbon). This allows the parts to be soft enough to undergo further cold working without fracturing. Process annealing is done by raising the temperature to just below the FerriteAustenite region, line A 1 on the diagram. This temperature is about 727 ºC (1341 ºF) so heating it

Killed Steel Carbon and oxygen react in the steelmaking process to form a gas. If the oxygen available for this reaction is not removed (deoxidized) prior to casting, the gaseous products continue to evolve during solidifiion. Deoxidation of the steel is accomplished by
Annealing is a process by which the property of steel is enhanced to meet the machinability requirements. Annealing is a process of heating the steel slightly above the critical temperature of steel i.e. 723 Degree Centigrade and allowing it to cool down very slowly. There are various types of annealing. They are as follows: full annealing, process annealing, stress relief annealing
