一种具有良好抛光性能的铁素体不锈钢及其制造方法
摘要：
一种具有良好抛光性能的铁素体不锈钢及其制造方法，其成分重量百分比为：C≤0.015%，N≤0.020%，Si≤0.5%，Mn≤0.5%，P≤0.030%，S≤0.010%，Cr18～22%，Cu0.30～0.50%，Ni≤0.30%，Nb0.3～0.5%，Al≤0.002%，O≤0.005%，其余为Fe和不可避免杂质。本发明通过用Nb稳定化、控制钢中的氧含量及夹杂物类型，避免微米级第二相的析出及脆性夹杂的生成，以保证铁素体不锈钢的抛光性能。
摘要（英）：

The invention relates to ferrite stainless steel with good polishing performance and a manufacturing method thereof. The ferrite stainless steel comprises the following components in percentage by weight: not more than 0.015% of C, not more than 0.020% of N, not more than 0.5% of Si, not more than 0.5% of Mn, not more than 0.030% of P, not more than 0.010% of S, 18-22% of Cr, 0.30-0.50% of Cu, not more than 0.30% of Ni, 0.3-0.5% of Nb, not more than 0.002% of Al, not more than 0.005% of O and the balance of Fe and inevitable impurities. According to the manufacturing method provided by the invention, by using Nb for stabilization and controlling the oxygen content and the type of inclusions in the steel, the precipitation of a micro-sized second phase and the generation of brittle inclusions can be avoided, so that the polishing performance of the ferrite stainless steel can be ensured.
