<p>PURPOSE: A high-strength steel plate with high formability and galvanizing property and a manufacturing method thereof are provided to secure corrosion resistance of a steel plate at low cost by employing hot-dip galvanization. CONSTITUTION: A high-strength steel plate with high formability and galvanizing property comprises two or more selected from a group and the rest Fe(Iron) and inevitable impurities, where the group consists of C(Carbon) 0.15~0.25wt.%, Si(Silicon) 0.30~0.55wt.%, Mn(Manganese) 1.50~2.50wt.%, Al(Aluminum) 0.50~1.50wt.%, Nb(Niobium) 0.01~0.05wt.%, Ti(Titanium) 0.02~0.10wt%, Ni(Nickel) 0.10~0.30wt.%, and Cu(Copper) 0.10~0.30wt.%.</p> |
