② 可提供特定的硫含量范围以改善特定的性能:为改善切削加工性,建议硫含量控制范围为0.015%~0.030%;为改善焊接性,控制范围为0.008%~0.020%,为改善抛光性,控制最大0.015%。
③当有特殊原因(如热加工或低磁导率)需要减少铁素体含量时,最大Ni含量可按下列数量增加:序号1和32为0.50%;序号2、16、17、19、20、25、26、27和31为1.00%;序号为21、22为1.50%。
④Cu可增加到1.00%。

②可提供特定的硫含量范围以改善特定的性能:为改善切削加工性,建议硫含量控制范围为0.015%~0.030%;为改善焊接性,控制范围为0.008%~0.020%,为改善抛光性,控制最大0.015%。
③当切削性特别重要时,S可增加至0.045%。
④Cu可增加到1.00%。
⑤取得专利的牌号。
⑥对于某些用途,如可焊性或高强度钢丝,C最大可为0.12%。
