How many types of annealing heat treatment did you know?
Annealing is a heat treatment process by which the steel and alloys are heated to a suitable temperature for a certain period of time and then allowing it slowly cooled (furnace cooling). The purpose of annealing is to transform steel from Austenite to Pearlite, reduce hardness and increase ductility, facilitate machining and cold deformation, and at the same time uniform […]
