Abstract
Three Avesta Sheffield steels, 254 SMO, 654 SMO and SAF 2507, have been tested in seawater heated to 55 degrees C. In a first test the specimens were exposed in a water which was continuously chlorinated with 2 ppm. The corrosion conditions were very severe and crevice corrosion was observed in all three steels. Pitting corrosion occurred in the welds of 254 SMO and SAF 2507 but no in 654 SMO. In a second test the continuous chlorination was preceded by a period with intermittent chlorination. During this period the passivity of the steels was improved and after subsequent exposure to continuously chlorinated water the degree of corrosion was strongly reduced. Only 654 SMO was completely resistant to crevice corrosion in flange connections and for pitting corrosion in girth welded pipes are discussed. 9 refs, 27 figs, 7 tabs
