Title:
表面仕上げされた鋼板およびこれらの製造方法
Document Type and Number:
Japanese Patent JP6779862
Kind Code:
B2
Abstract:
A surface-finished steel sheet, in some examples cold-rolled thin steel sheet, includes a metallic corrosion-resistant layer that may comprise more than 40% by weight aluminum and iron. So that that corrosion-resistant layer has high formability, especially cold formability, and hence significantly improved adhesion on forming, the corrosion-resistant layer may comprises nickel, wherein nickel-containing phases are located at a transition from the corrosion-resistant layer to a base material of the steel sheet. The nickel content of the corrosion resistant layer may be in a range from 5 to 30% by weight. Further, a method for producing a surface-finished steel sheet of this kind is also disclosed. In some examples, a nickel layer may be applied to a steel sheet, preferably cold-rolled thin steel sheet in the form of flat steel product, prior to hot-dip coating the steel sheet with a liquid aluminum melt or with a liquid melt of aluminum-based alloy.
