摘要： A tin-free steel strip comprising a steel strip, 40 to 150 mg/m.sup.2 of a metallic chromium layer on the steel surface, and 5 to 25 mg/m.sup.2 of a chromium compound containing layer thereon wherein the metallic chromium layer contains a plurality of protrusions, exhibits improved corrosion resistance and weldability and is thus useful in the manufacture of welded cans. Preferably, 1.times.10.sup.11 to 1.times.10.sup.14 protrusions having a diameter of 5 to 1000 nm at the base thereof are present per square meter of the metallic chromium layer surface. The tin-free steel strip is produced by chromium plating a steel strip in an aqueous solution containing CR.sup.6+ preferably to a weight of 40 to 140 mg/m.sup.2, subjecting the chromium plated strip to anodic electrolysis, preferably at an eectricity quantity of 0.1 to 10 C/dm.sup.2, and subjecting the strip to a cathodic treatment in an aqueous solution containing Cr.sup.6+ and a chromium plating aid so as to deposit additional metallic chromium, preferably in a weight of 10 to 60 mg/m.sup.2.

摘要： The present invention provides a method for producing a thin cold rolled steel sheet, which is adapted to be formed into, for example, an external automotive plate. The method includes an appearance-finishing step by bake-coating as a final step after drawing (such as press molding), and has a remarkably high baking hardenability. The baking hardenability is a property for improving the yield strength due to the heating during the bake coating treatment and is particularly advantageous for producing a light weight automobile and for compensating the deterioration of dent resistance of the automotive plate due to the lowering of its weight, (without deteriorating the r value). The latter is an indication of the press moldability of the thin steel sheet. Furthermore, the present invention discloses an effective compounding amount of Ti which acts to fix C, S and N contained in the steel, and a continuous annealing condition properly selected depending upon the effective amount of Ti.
