ML35Mn Cold Heading Steel Bar
ML35Mn Cold heading steel molding steel, the cold heading is used at room temperature one or more impact loading, widely used in the production of screws, pins, nuts and other standard parts.
Cold heading process can save raw materials, reduce costs, but also by cold hardening to improve the tensile strength of the workpiece to improve performance, cold forging steel must have a good cold forging performance, steel S and P and other impurities to reduce the Steel surface quality requirements are strict, often using high-quality carbon steel, if the steel carbon steel is greater than 0.25%, should be ball annealing heat treatment to improve the cold heading performance of steel.
