這是美標牌號，對應的國內牌號沒有，最接近的是Y15,Y13, 但是不能等同，這種材料多為進口。
1215鋼材 1215易切削鋼為環保料,與12L14相比不含鉛及不含有對環境有害物質,切削性良好.適合一般電鍍軸心、切削用料及一般零件.1215由于精度準確,表面狀況良好,易削切鋼產品可直接使用,如噴涂,打砂,打彎,鉆孔,也可按實際要求精拉之后直接電鍍,免去了大量機加工時間及節省配置加工機械的費用.
1215鋼材用途：
主要用于制作受力較小而對尺寸和光潔度要求嚴格的儀器儀表、手表零件、汽車、機床和其他各種機器上使用的，對尺寸精度和光潔度要求嚴格，而對機械性能要求相對較低的標準件，如齒輪、軸、螺栓、閥門、襯套、銷釘、管接頭、彈簧座墊及機床絲杠、塑料成型模具、外科和牙科手續用具等。
