摘要： PROBLEM TO BE SOLVED: To provide a high corrosion resistance and high strength fine wire having high tensile strength.
SOLUTION: By cold wire drawing in a third wire drawing stage 26 and aging in the subsequent aging stage 28, a high corrosion-resistance fine wire 10 having tensile strength sufficiently higher than that of a base material can be obtained. Also, since the alloy composition in the base material is essentially consisting of Ni, suitable magnetic properties, i.e., a low magnetic permeability of about 1,003 can be obtained. Further, the magnetic permeability is not increased by cold or warm plastic working differently from the case of austenitic stainless steel represented by SUS 304. Also, the Ni based alloy composition in the base material comprises 30 to 45 (weight)% Cr, high corrosion resistance can be obtained. Further, the Ni based alloy composition in the base material does not comprise expensive metals, an inexpensive corrosion resistance and high strength fine wire can be obtained.

摘要翻译：要解决的问题：提供具有高拉伸强度的高耐腐蚀性和高强度细线。解决方案：通过在第三拉丝段26中进行冷拉丝并在随后的老化阶段28中老化，可以获得具有足够高于基材的拉伸强度的高耐腐蚀性细线10。此外，由于基材中的合金组成基本上由Ni组成，因此可以获得合适的磁性，即低磁导率约为1,003。此外，与由SUS304表示的奥氏体不锈钢的情况不同，冷或暖塑料的磁导率不会增加。另外，基体材料中的Ni基合金组成含有30〜45（重量）％的Cr，高腐蚀性可获得电阻。此外，基材中的Ni基合金组成不包含贵金属，可以获得廉价的耐腐蚀性和高强度的细线。版权所有（C）2007，JPO＆INPIT
