Title:
Fe-ELECTROPLATED STEEL SHEET, ELECTRODEPOSITION COATED STEEL SHEET, AUTOMOBILE COMPONENT, METHOD FOR MANUFACTURING ELECTRODEPOSITION COATED STEEL SHEET, AND METHOD FOR MANUFACTURING Fe-ELECTROPLATED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2021/200412
Kind Code:
A1
Abstract:
Provided is an Fe-electroplated steel sheet having exceptional chemical conversion processing properties, exceptional post-coating corrosion resistance evaluated through a warm salt water immersion test, and exceptional characteristics for resistance to cracking during resistance welding in a welding part when a zinc-plated steel sheet is used as a counterpart sheet. An Fe-electroplated steel sheet having: a Si-containing cold-rolled steel sheet that contains 0.5-3.0 mass% (inclusive) of Si; and an Fe-based electroplating layer formed on at least one surface of the Si-containing cold-rolled steel sheet, the adhesion amount of the Fe-based electroplating layer per surface being 15.0 g/m2 or higher.
