20110168563 | TIN-PLATED STEEL SHEET AND METHOD FOR MANUFACTURING THE SAME - A tin-plated steel sheet includes a steel sheet; an Sn-containing plating layer in which the mass per unit area of Sn is 0.05 to 20 g/m | 07-14-2011 |
20130130055 | COATED STEEL SHEET, METHOD FOR PRODUCING THE SAME, AND RESIN-COATED STEEL SHEET OBTAINED USING THE SAME - A coated steel sheet includes a corrosion-resistant coating composed of at least one layer selected from the group consisting of a Ni layer, a Sn layer, an Fe—Ni alloy layer, an Fe—Sn alloy layer, and an Fe—Ni—Sn alloy layer disposed on at least one surface of a steel sheet, and an adhesive coating disposed on the corrosion-resistant coating, the adhesive coating containing Zr and further containing at least one metal element selected from the group consisting of Co, Fe, Ni, V, Cu, Mn, and Zn, in total, at a ratio by mass of 0.01 to 10 with respect to Zr. The coated steel sheet has excellent humid resin adhesion and corrosion resistance, in which streaky surface defects do not occur. | 05-23-2013 |
20130206285 | MANUFACTURING METHOD FOR STEEL SHEETS FOR CONTAINERS - A manufacturing method for steel sheets for containers produces steel sheets with excellent film adhesion qualities. In a method for manufacturing steel sheets upon which is formed a chemical conversion coating having a metal Zr content of 1-100 mg/m | 08-15-2013 |
20130209827 | STEEL SHEET FOR CONTAINERS AND MANUFACTURING METHOD FOR SAME - A steel sheet for containers that has excellent film adhesion qualities, and has; a chemical conversion coating formed by immersing or subjecting to electrolytic treatment a steel sheet in a solution containing Zr ions, F ions, with adhesion amount of 0.1 to 100 mg/m | 08-15-2013 |
20130209829 | STEEL SHEET FOR CONTAINERS - Disclosed is a steel sheet for containers that maintains excellent corrosion resistance even when a surface treatment that replaces a chromate treatment has been conducted, and that has excellent film adhesion qualities and appearance. This steel plate for containers has, on at least one surface thereof, a chemical conversion coating including at least two coatings selected from a zirconium coating that contains zirconium and has a metal zirconium content of 0.1-9 mg/m | 08-15-2013 |
20130209830 | STEEL SHEET FOR CONTAINERS AND MANUFACTURING METHOD FOR SAME - A manufacturing method for steel sheets for containers produces steel sheets with excellent film adhesion qualities. This steel sheet for containers has, on a steel sheet, a chemical conversion coating with a metal Zr content of 1-100 mg/m | 08-15-2013 |
20130216714 | MANUFACTURING METHOD FOR STEEL SHEETS FOR CONTAINERS - Disclosed is a manufacturing method for steel sheets for containers that enables reliable, continuous manufacture of steel sheets, with excellent film adhesion qualities, for containers. The manufacturing method for steel sheets for containers is a method in which a film containing Zr is formed on the surface of the steel sheets by immersing, and/or subjecting to electrolytic treatment, the steel sheets in a solution containing Zr ions, F ions, and at least one reaction accelerating component selected from a group including Al ions, boric acid ions, Cu ions, Ca ions, metal Al, or metal Cu. | 08-22-2013 |
20130216858 | STEEL SHEET FOR CONTAINERS AND MANUFACTURING METHOD FOR SAME - A steel sheet for containers that has excellent film adhesion qualities, and has a Zr compound film formed thereupon by immersion in or electrolytic treatment with a solution containing Zr ions, F ions, and hydroxylic acid, the Zr compound film being applied in an amount such that the metal Zr content is 0.1-100 mg/m and the F content is no more than 0.1 mg/m | 08-22-2013 |
