本发明中，冷锻性，切削性，它是一个对象，以获得具有相同的时间的铁素体不锈钢丝耐腐蚀。 对于耐腐蚀性，具有耐腐蚀性的基于Cr铁素体不锈钢，在焊接，因为在Cr碳氮化物沿晶界形成的，因为在生成Cr缺乏层部分降解的耐腐蚀性 到。 因此钛，Nb添加，钛，铌的碳氮化物的Cr限制碳氮化物的析出在被优先析出，抑制Cr缺乏层的形成。 虽然最好是在切削加工许多夹杂物，较好的夹杂物少，冷锻性逆转。 本发明人通过比较大的夹杂物存，以确保在钢丝的表面层部分的机械加工，钢丝中央通过相对小的夹杂物，以确保韧性， 以确保冷锻性，冷锻性，切削性，能够获得具有相同的时间的铁素体不锈钢丝耐腐蚀。

The present invention, cold forgeability, machinability, it is an object to obtain a ferritic stainless steel wire having the same time corrosion-resistant.
For corrosion resistance, has a corrosion resistance of the Cr-based ferritic stainless steel, in the welding unit, because the Cr carbonitrides are formed along the grain boundaries, partially degraded corrosion resistance due to Cr-depleted layer is generated to. Therefore Ti, added Nb, Ti, carbonitrides of Nb restricts the precipitation of Cr carbonitride by causing preferential precipitation, inhibits the formation of Cr-depleted layer.
Although it is better that there are many inclusions in the cutting ability, better small inclusions in the cold forging properties to reverse. Accordingly, the present inventors have, to ensure machinability by relatively large precipitates inclusions in the surface layer of the steel wire, the steel wire central portion, ensures toughness by relatively small inclusions, to ensure cold forgeability, cold forgeability, machinability, it was possible to obtain a ferritic stainless steel wire having the same time corrosion-resistant.
