STEEL FOR FASTENERS | |||||||||||||||||||||||||||||||||||||
Steels dedicated for the manufacturing of mechanical fastening components such as screws, bolts and nuts that can be produced by machining with chip-forming machining, or by heating or cooling plastic deformation: nowadays the cold-heading process is the most used. Extrusion, rolling and cold-heading have an important role among the pressing processes, because assure to manufacture pieces with complex shape and characteristic. In order to guarantee the needed plasticity to the steel for the above described pressing processes, it becomes important the steel annealing that has to insure to the product a globular structure suitable for making the steel wire deformation easier. Our long experience in thermal treatment is supported by a steel annealing plant updated and innovative that provides the best and steady results through the time. |
