Claims
- 1. A method for producing a stainless steel wire, comprising the steps of:
- plating nickel having a thickness in the range of 1 .mu.m to 5 .mu.m on a stainless steel core wire comprising carbon (C) in an amount of not more than 0.15% by weight, silicon (Si) in an amount of not more than 1.00% by weight, manganese (Mn) in an amount of not more than 2.00%, nickel (Ni) in an amount of from not less than 6.50% by weight to less than 14.00% by weight and chromium (Cr) in an amount of from not less than 17.00% by weight to less than 20.00% by weight;
- generating an inorganic salt coat film comprising at least one of potassium sulfate and borax (borate) and free from chlorine (Cl) and fluorine (F) from an aqueous solution to be deposited on said nickel plate layer; and
- drawing said wire to a reduction of area of not less than 60%.
- 2. The producing method according to claim 1, wherein the amount of said carbon is not less than 0.05% by weight, the amount of said silicon is not less than 0.1% by weight, and the amount of said manganese is not less than 0.1% by weight.
- 3. A stainless steel wire comprising:
- a stainless steel core wire comprising carbon (C) in an amount of not more than 0.15% by weight, silicon (Si) in an amount of not more than 1.00% by weight, manganese (Mn) in an amount of not more than 2.00%, nickel (Ni) in an amount of from not less than 6.50% by weight to less than 14.00% by weight and chromium (Cr) in an amount of from not less than 17.00% by weight to less than 20.00% by weight;
- a nickel (Ni) plate layer having a thickness of from not less than 0.3 .mu.m to not more than 1.7 .mu.m on said stainless steel core wire; and
- an inorganic salt coat film comprising at least one of potassium sulfate and borax (borate) and free from chlorine (Cl) and fluorine (F) deposited on said nickel layer;
- wherein a tensile strength of said stainless steel wire is not less than 160 kgf/mm.sup.2 and a surface roughness thereof is in the range of 0.80 to 12.5 .mu.mRz.
- 4. The stainless steel wire according to claim 3, wherein said surface roughness is from 1.0 to 10.0 .mu.mRz.
- 5. The stainless steel wire according to claim 3, wherein the amount of said carbon is not less than 0.05% by weight, the amount of said silicon is not less than 0.1% by weight, and the amount of said manganese is not less than 0.1% by weight.
