Abstract:
The present invention provides a steel wire rod having a lubricating coating film, which can achieve both workabilities such as wire drawability, spike property and ball ironing property, and corrosion resistance such as long-term rust prevention property; and a method for producing the same. Disclosed are a steel wire rod having a coating film containing no phosphorus, wherein the coating film includes a lower layer coating film composed of oxide and/or hydroxide of zirconium and having a film thickness of 1.0 to 200 nm, and an upper layer coating film containing silicon and tungsten, in order from a steel wire rod side, a mass ratio of tungsten/silicon being in a range of 1.3 to 18; and a method for producing the above steel wire rod, which includes bringing an aqueous chemical conversion treatment solution, which has a pH in a range of 2.5 to 5.0 and contains a water-soluble zirconium compound dissolved therein, into contact with a surface of a steel wire rod to form a lower layer coating film.

Abstract:
In order to obtain a cold rolled steel sheet having excellent press formability, a cold rolled steel sheet has, on a surface thereof, an organic-inorganic composite film containing: an organic resin; and a crystalline layered material. The organic-inorganic composite film has an average film thickness of 0.10 to 2.0 μm and contains 0.5 part or more by weight of the crystalline layered material as a solid with respect to 100 parts by weight of a solid of the organic resin. The crystalline layered material preferably is, for example, a layered double hydroxide represented by [M2+1-xM3+x(OH)2][An−]x/n.zH2O, where: M2+ is one or more of Mg2+, Ca2+, Fe2+, Ni2+, and Zn2+; M3+ is one or more of Al3+, Fe3+, and Cr3+; and An− is one or more of OH−, CO32−, Cl−, and (SO4)2−.
