<p>Disclosed is a hot-dip galvanized steel sheet which is characterized in that the steel sheet before galvanization contains, in mass%, 0.06-0.15% of C, 1-3% of Mn, 0.01-0.05% of P, 0.03-1% of Cr, 0.03-1% of Mo and 0.02-0.15% of Al. It is also characterized in that the Si content and the S content in the steel sheet before galvanization are respectively suppressed to 0.2% or less (including 0%) and 0.03% or less (including 0%). Further, the value K calculated by the formula (1) below is not less than-2.0. K = 3 x [Mo]-5 x [Cr] (1) In the above formula, [Mo] and [Cr] respectively represent the contents (mass%) of Mo and Cr.</p> |
