具有几乎全珠光体的中碳钢线材可以不经过铅浴淬火直接拉拔到 1.0mm钢丝,通过控制奥氏体晶粒尺寸和转变温度可得到这种组织,但在斯太尔摩(Stelmor)生产线上控制这种组织有些困难,因此,添加合金元素是用于斯太尔摩生产线上增加线材的珠光体体积分数的有效方法。Cr和Mn是减少先共 Medium carbon steels with almost full pearlite can be drawn directly to 1.0 mm steel wire without quenching of the lead bath and can be obtained by controlling the austenite grain size and the transition temperature but at Stelmor Controlling this organization on the production line is somewhat difficult, so the addition of alloying elements is an effective method for increasing the volume fraction of pearlite in wire production on the Steyr line. Cr and Mn are reduced first
