THE PROCESS
Heat treatment involves controlled heating and cooling of metal to achieve desired physical and mechanical properties, without changing the shape of the product. NAF’s heat treatment techniques include annealing, normalizing and tempering, solution treatment, quenching (polymer, oil and water) and stress relieving. Heat treatment ensures product performance by achieving the balance of properties of strength, hardness, toughness, ductility, impact strength and microstructure required by customer specification.
