THE BEHAVIOUR OF STRUCTURAL STEELS IN SEAWATER

One of the many factors affecting the corrosion of structural steels used for ships and other structures in contact with seawater is the steel itself. Investigations extending over the past 20 years have shown that by suitable alloying, the corrosion resistance of such steels can be considerably improved; among the most effective alloying elements for this purpose are silicon, chromium, and copper, while nickel has little effect. Steels with about 1%Si, up to 3%Cr, and up to 1%Cu can achieve a resistance to seawater that, depending on environmental conditions, is three to six times that of unalloyed structural steel. The Author (of Stahlwerke Peine-Salzgitter AG) discusses these developments, including their economic aspects, in some detail. Order from BSRA as No. 49,404.
