PURPOSE: A hot strip with high corrosion resistance against seawater is provided, which shows superior resistance against salt attacks commonly observed in steel structures around seawater surface. CONSTITUTION: The hot strips with high corrosion resistance against seawater comprises C 0.03-0.10wt.%, Si 0.10-0.50wt.%, P 0.02-0.05wt.%, Mn 0.50-1.0wt.%, Cr 1.0-2.0wt.%, Al 0.01-0.07wt.%, S 0.01wt.% or less, Cu 0.1-0.3wt.%, Ni 0.1-0.3wt.%, Nb 0.03wt.% or less, Ti 0.02wt.% or less, and balance of Fe, and other inevitable impurities where the ratio of Mn/S is higher than 150.
