Document Type and Number:
WIPO Patent Application WO/2004/067801
Kind Code:
A1
Abstract:
An oil tempered steel wire, characterized in that it comprises a wire material and, formed on the surface thereof, a coating film comprising one or more inorganic salts selected from the group consisting of a sulfate, a silicate and a borate. The coating film optionally further comprises fats and oils and/or a soap exhibiting lubricity. The oil tempered steel wire has a coating film exhibiting satisfactory heat resistance and good lubricity and thus can secure good coiling workability even in the case of a high strength wire or a wire having a heteromorphic section.
