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.
