Abstract (en)
[origin: EP0608466A1] A process of producing a steel wire for automatic coiling, said process comprising the steps of: providing Ni plating having a thickness of from 1 to 5 mu m to a steel wire containing 0.15% by weight or less of carbon, 1.00% by weight or less of sulfur, 2.00% by weight or less of manganese, 6.50% by weight or more and less than 14% by weight of nickel, and from 17.00 to 20.00% by weight of cromium; coating thereon a synthetic resin containing a halogen; drawing said steel wire to a reduction of cross-sectional area of at least 60%, with adjusting the surface roughness thereof to the range of from 0.8 to 12 s. A steel wire for automatic coiling comprising a steel wire containing 0.15% by weight or less of carbon, 1.00% by weight or less of sulfur, 2.00% by weight or less of manganese, 6.50% by weight or more and less than 14% by weight of nickel, and from 17.00 to 20.00% by weight of cromium, having thereon Ni plating having a thickness of from 0.3 to 1.7 mu m and having further coated thereon a synthetic resin containing a halogen, the tensile strength of the wire being at least 160 kgf/mm<2> and the surface roughness thereof being from 0.8 to 12 s.
