PURPOSE: To manufacture the titled stainless steel-coated steel wire having excellent corrosion resistance and strength and good adhesiveness by wiredrawing a clad material obtained by coating stainless steel on a core wire of a carbon steel wire, patenting the wire under specified conditions, and wiredrawing into a wire having specified diameter.
CONSTITUTION: A stainless steel tape 2 is wound on a high-carbon steel wire 3 with a forming roll 4, and the butted surface of the stainless steel tape 2 is welded by a welder 5 to form a coated layer. Then the coated wire is passed through a wiredrawing machine 6, drawn at ≥70% reduction of area, heated at ≥900°C in a heater 7, passed through a molten lead bath 8, and patented to generate metallic bonding between the core mateial steel wire and the clad material. The wire is then wiredrawn in a wiredrawing machine 9 into a wire having desired wire diameter which is heated at 300W400°C in a heater 10 while exerting tensile force on the wire so that the wire may be provided with ≥0.5% tensile strain in a caterpillar device 12. The wire is cooled by a water cooler 11, and then wound by a winding machine 13.
