Vedclass · Answer

(B) Annealing is a heat treatment process that involves heating a material to a specific temperature,holding it at that temperature for a suitable amount of time,and then cooling it slowly. In the context of steel,it involves heating the steel to a temperature above its critical range (bright redness) and then allowing it to cool slowly,typically in a furnace. This process reduces hardness,increases ductility,and helps eliminate internal stresses.
