在本研究中，通过使用 CA6164 车床进行切削性能测试，研究了无铅可切削奥氏体不锈钢。将所开发合金的冶金性能、切削加工性能和机械性能与常规奥氏体不锈钢1Cr18Ni9Ti进行了比较。结果表明，所研制的无铅可切削奥氏体不锈钢中的夹杂物主要由MnS、Bi、CuO和Ti4C2S2组成。铋是提高奥氏体不锈钢切削加工性的重要因素，与铅相比具有明显的优势。合金添加剂的存在有助于提高所开发的奥氏体不锈钢的切削加工性。无铅可切削奥氏体不锈钢的机械性能表现出抗拉强度和总伸长率的良好组合，尽管夹杂物对其产生的不利影响较小。
In this study, non-lead machinable austenitic stainless steel was investigated through performing the machinability tests using a CA6164 lathe. The metallurgical properties, machinability and mechanical properties of the developed alloy were compared with those of the conventional austenitic stainless steel 1Cr18Ni9Ti. The results have shown that the inclusions were composed of MnS, Bi, CuO and Ti4C2S2 in the developed non-lead machinable austenitic stainless steel. Bismuth is an important factor to improve the machinability of austenitic stainless steel, and it has a distinct advantage over lead. The presence of alloying additives contributes to the improvement of the machinability of the developed austenitic stainless steel. The mechanical properties of non-lead machinable austenitic stainless steel exhibit a good combination of tensile strength and total elongation, despite the inclusion had a minor detrimental effect on them.
