    Hot Selling for Large Seamless Steel Tube - Cold heading steel high quality wire plate and bar – Lu

    Introduction Cold heading steel is used for forming steel. Cold heading is the use of one or more impact loads at room temperature. It is widely used in the production of standard parts such as screws, pins, and nuts. The cold heading process can save raw materials, reduce costs, and improve the tensile strength and performance of the workpiece through cold work hardening. The steel used for cold heading must have good cold upsetting performance, and the content of impurities such as S and P ...
