STEEL WIRE MATERIAL HAVING LUBRICATION COATING EXCELLENT IN CORROSION RESISTANCE AND PROCESSABILITY

摘要

PROBLEM TO BE SOLVED: To provide a steel wire material having a lubricant coating capable of achieving both of processability such as wire drawability, spike property, ball ironing properties and decladding properties and corrosion resistance such as long-term rush preventive properties.SOLUTION: There is provided a steel wire material containing water-soluble silicate and water-soluble tungstate with a mass ratio of water-soluble silicate/water-soluble tungstate in a range of 0.7 to 10 and having a lubrication coating without phosphorous on a surface.
