<P>PROBLEM TO BE SOLVED: To provide a high strength hot dip galvanized steel sheet that has an excellent bendability and also has an excellent surface nature free from a non-plated region. <P>SOLUTION: The hot dip galvanized steel sheet includes a hot dip galvanization layer on a steel sheet surface. The steel sheet includes a chemical composition containing less than 0.010 mass% of sol. Al, 0.0001-0.05 mass% of Bi, and 1.0-5.0 mass% of Si and Mn, and has a tensile strength of 1,180 MPa or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
