Research projects have demonstrated the possibility of developing lowalloy steels with a better resistance to sea water corrosion than Fe510 steel, with the same or better mechanical properties. In the study reported here four experimental steels with varying Al and Cr levels (0.4% to 0.8% and 1% to 1.5% respectively) were examined: all steels tested show better corrosion resistance compared to Fe510; it was shown that the steel with 0.8% Al and 1% Cr provides the best corrosion resistance; the lower corrosion rate of high strength low alloy (HSLA) steels may be attributed to the tendency of the Al oxides incorporated in the corrosion layer to passivate the steel surface; optimum protective properties can be achieved by combining this low alloy steel with a coating containing Al as anti-corrosion pigment.
