There are several processes of annealing like bright annealing
, process annealing, recrystallization annealing, sub critical annealing, spheroid annealing, isothermal annealing, full annealing, etc. Each process is instrumental in producing different varieties of steel that can be used for different industry requirements. For instance, spheroid annealing is used to produce alloys of steel, and recrystallization annealing is done to impart a distinguishing grain structure to the element.
