Title: High strength hot dip galvanized steel sheet excellent in plating suitability
Inventor: MIYAOKA YUKINORI
IPC: C23C2/02
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To produce a high strength hot dip galvanized steel sheet having superior plating suitability equal to that of a plane steel by allowing, in a hot dip galvanized steel sheet containing specific amounts of Si, an oxide to remain in the crystalline grain boundaries right under a plating layer. SOLUTION: A hot dip galvanizing layer is formed at least on one side of a high tensile strength steel sheet containing 0.1-2.0wt.% Si, and this plating layer is alloyed if necessary. In this high strength hot dip galvanized steel sheet, an oxide is allowed to remain in the crystalline grain boundaries right under the plating layer. This intergranular oxide can be obtained by raising coiling temp. and decreasing cooling velocity at the time of hot rolling to grow the oxide, removing only the mill scale on the oxide by pickling, and allowing the oxide to remain. By the presence of this oxide, the surface concentration of Si, etc., can be prevented and wettability at the surface of the steel sheet can be improved, and as a result, uncoating resistance and plating adhesion can be improved.
