Hot-dip aluminum-coated steel wire

Abstract

A hot-dip aluminum-coated steel wire including a steel wire having a diameter of 0.1 to 0.4 mm on which a plating layer is formed, wherein an elongation at break of the hot-dip aluminum-coated steel wire is 5 to 30%, and a ratio of an average diameter of the steel wire which is taken out from the hot-dip aluminum-coated steel by removing the plating layer per 100 mm in length of the steel wire to the minimum diameter of the steel wire satisfies the formula: [minimum diameter/average diameter]≥[1−(elongation at break (%)/100)], and a method for producing a hot-dip aluminum-coated steel wire including wire-drawing a hot-dip aluminum-coated steel wire so that a ratio of an average diameter of the steel wire which is taken out from the hot-dip aluminum-coated steel by removing the plating layer per 100 mm in length of the steel wire to the minimum diameter of the steel wire satisfies the above-mentioned formula, and an elongation at break of the hot-dip aluminum-coated steel wire is 5 to 30%.

1 . A hot-dip aluminum-coated steel wire comprising a steel wire having a diameter of 0.1 to 0.4 mm, on which a plating layer is formed, wherein an elongation at break of the hot-dip aluminum-coated steel wire is 5 to 30%, and a ratio of an average diameter of the steel wire which is taken out from the hot-dip aluminum-coated steel by removing the plating layer per 100 mm in length of the steel wire to the minimum diameter of the steel wire satisfies the formula (I):
   [minimum diameter/average diameter]≥[1−(elongation at break (%)/100)]  (I).
   
     
     
         2 . A method for producing a hot-dip aluminum-coated steel wire comprising a steel wire having a diameter of 0.1 to 0.4 mm, on which a plating layer is formed, which comprises wire-drawing a hot-dip aluminum-coated steel wire so that an elongation at break of the hot-dip aluminum-coated steel wire is 5 to 30%, and a ratio of an average diameter of the steel wire which is taken out from the hot-dip aluminum-coated steel by removing the plating layer per 100 mm in length of the steel wire to the minimum diameter of the steel wire satisfies the formula (I):
   [minimum diameter/average diameter]≥[1−(elongation at break (%)/100)]  (I).
