Title:
RUST-PROOF STEEL SHEET AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/035847
Kind Code:
A1
Abstract:
Provided is a rust-proof steel sheet having on at least one side an organic and/or inorganic coating layer, wherein the coating layer of the portion to be spot welded is thinner than the coating layer of the portion not to be spot welded. Also provided is a method for producing the rust-proof steel sheet. The rust-proof steel sheet has sufficiently low electrical resistivity at the welded parts that sound welded parts can be formed, and has both spot weldability and corrosion resistance.
