The invention belongs to the technical field of stainless steel materials, and particularly discloses a novel austenite free-cutting stainless steel material. The novel austenite free-cutting stainless steel material comprises the following components in percentage by weight: less than or equal to 0.15% of C, 14-17% of Cr, 16-18% of Mn, 0.15-0.25% of S and the balance of iron and inevitable impurity elements. Manganese is used for replacing nickel, the manganese content is increased to 16-18%, meanwhile, through optimization of the C, Cr and S element content, novel austenitic stainless steel which is non-magnetic and has the elongation being about 47% is formed, nickel can be completely replaced, plasticity is not affected, good machining performance is obtained, meanwhile, cost is effectively reduced, strength is high, abrasion resistance is good, and corrosion resistance is good. The stainless steel can be used for manufacturing ball-point pen refills, keys and other elements with high machining precision requirements, and has obvious advantages compared with existing 416 and 303 common sulfur-containing free-cutting stainless steel.
本发明属于不锈钢材料技术领域，具体公开了一种新型奥氏体易切削不锈钢材料，包括以下重量百分比的成分：C≤0.15％，Cr 14‑17％，Mn 16‑18％，S 0.15‑0.25％，其余为铁和不可避免的杂质元素。本发明以锰替代镍，将锰含量提高至16‑18％，同时通过C、Cr、S元素含量的优化，形成了一种无磁性、延伸率在47％左右的新型奥氏体不锈钢，能够完全替代镍，而不影响塑性，获得良好加工性能的同时有效降低了成本，而且强度高、耐磨性好、耐腐蚀性好，可用于制作圆珠笔芯、钥匙等加工精度要求高的元件，与现有的416和303两种常见的含硫易切削不锈钢相比，具有明显优势。
