Why normalising is the final product in the heat treatment process?
How does normalising differ from annealing?
While both annealing and normalising are heat treatment processes, they differ in their cooling methods. Annealing involves heating the metal and then allowing it to cool slowly, often in a furnace or controlled atmosphere. Normalising, on the other hand, involves cooling the metal in still air, which can result in a faster cooling rate and a more uniform grain structure. Normalising is typically used for medium- to high-carbon steels, while annealing is used for a variety of metal alloys.
