Abstract (en)
[origin: EP1990437A1] Anti-corrosion steel for ship is provided at low cost, which exhibits excellent corrosion resistance without depending on a surface condition of steel even under severe corrosion environment such as a ballast tank of a ship. Anti-corrosion steel for ship contains, in mass percent, C of 0.03 to 0. 25%, Si of 0. 05 to 0. 50%, Mn of 0.1 to 2.0%, P of 0.025% or less, S of 0.01% or less, Al of 0.005 to 0.10%, W of 0.01 to 1.0%, Cr of 0.01% or more and less than 0.20%, and furthermore contains as needed one or two selected from Sb of 0.001 to 0.3% and Sn of 0.001 to 0.3% and/or one or at least two selected from Ni of 0.005 to 0.25%, Mo of 0.01 to 0.5%, and Co of 0.01 to 1.0%, and contains the remainder including Fe and inevitable impurities.
