冷拉碳素弹簧钢丝由于易成型和不经热处理便可直接缠绕弹簧的特点,广泛应用于钟表、仪表、纺织、交通运输、机器制造等各个行业。弹簧的加工性能和重要用途要求钢丝不仅具有高的抗拉强度、弹性极限,同时具有良好的韧性和耐疲劳性能。但在弹簧 Cold-drawn carbon spring steel wire can be directly wound around the spring because of its easy forming and without heat treatment. It is widely used in various industries such as watches, meters, textiles, transportation and machinery manufacturing. Spring processing performance and important applications require not only high tensile strength wire, elastic limit, but also has good toughness and fatigue resistance. But in the spring
