Compared to cold drawing process, the cold rolling for high precision bars has certain distinct advantages: better surface finish obtained. superior dimension control and higher metal yield.
前言：冷轧法生产的高精度钢材较冷拔法具有更好的表面质量、尺寸精度和高的收得率。
Material in Condition a may be given a final cold drawing for size control or finish, or both, slightly raising tensile strength.
条件A的材料可以通过冷拔来控制大小尺寸和表面质量，或两者。可稍微提高抗拉强度。
