Procedure of metal forming, altering the shape and/or structure of through drawing, extruding, hammering, pressing, rolling, spinning, and/or stretching. This procedure occurs at temperatures below the steel’s recrystallization point, typically room temperature . The metal’s composition changes during these processes, which causes hardness and tensile strength to be permanently increased. It also decreases ductility and impacts resistance, but enhances the surface finish.
