WELDABLE TYPE ORGANIC COMPOSITE PLATED STEEL SHEET WITH EXCELLENT CORROSION RESISTANCE AND PRESS MOLDABILITY
Document Type and Number:
Japanese Patent JP3276565
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a weldable type organic composite plated steel sheet having excellent corrosion resistances and press moldabilities of a general surface and a cut surface and excellent operability.
SOLUTION: A Zn-plated layer having an adhesion amount corresponding to 30 to 130 = plating adhesion amount (g/m)/thickness of steel sheet (mm), a chromate film having a total Cr adhesion amount of 10 to 150mg/m2, and an organic film having a thickness of 1 to 20μm are sequentially formed from the sheet side on one side surface or both side surfaces of the sheet. In this case, a conductive inorganic pigment ratio of the organic film is 1 to 40vol.%, non-chromium rustpreventive pigment ratio is 5 to 40vol.%, lubricant is 1 to 40vol.%, and its total sum is 7 to 65Vol.%.
