  • 关于SWC和65Nn,其实SWC里包含了65Nn。

  • SWC,能生产弹簧的钢丝的总称,他包含很多种牌号,所有的能做弹簧的钢丝的钢种都在它名下。它包含:70/80/60MN/70MN/T8MNA/T9A/65MN等钢种在内,SWC这个钢有多少种很少有人能说出一个详细的数字出来。

  • 如果是常规材料里谁更硬的话,那么一定是高碳钢硬一些。碳是决定钢材性能的主要元素,因为含碳量的变化直接引起晶体组织的变化。随着含碳量的增加,钢的强度和硬度增大。碳素结构钢,钢号开头两位表示钢的含碳量,因此上面例出的高碳钢里65Mn钢在他们里面并不是最硬的。

希望能帮助到您!谢谢!

65Mn弹性好于SWC:
S-STEEL;
W-WIRE;
C-CARBON
即碳素弹簧钢丝。
