ML15MNB steel cold heading steel carbon content is generally controlled by the lower limit is appropriate. Steel silicon content exceeds 0.10%, with the silicon content increases, the tensile strength of steel, the hardness increased, but low elongation, reduction of area decreased more significantly, it is not conducive to cold deformation. Moderate manganese content in steel can improve the shape and distribution of steel in the presence of sulfur, it will help improve steel cold formability. Grades and composed mainly of cold heading steel in Table 1.

Cold heading process can save raw materials ML35Mn complete specifications, reduce costs, and improve the tensile strength through work hardening ML35Mn work, improve performance, cold heading steel have its good cold upsetting performance in steel and other impurities S and P content decreased, the surface quality of steel demanding, often using high-quality carbon steel, carbon steel, if steel containing more than 0.25%, should be ball annealing heat treatment to improve the performance of cold heading steel.
