Comparative marine immersion corrosion of ship construction steels exposed in Arctic and temperate waters
Arctic waters present significant challenges for ship constructional steels. Mostly they are alloyed to meet strength and ductility conditions sufficient to ensure adequate structural safety conditions for low temperature conditions. However, their corrosion resistance characteristics are not well u...

Arctic waters present significant challenges for ship constructional steels. Mostly they are alloyed to meet strength and ductility conditions sufficient to ensure adequate structural safety conditions for low temperature conditions.

Although cathodic protection usually would be expected to be sufficient to maintain the steels in adequate condition, the unprotected corrosion behaviour under relatively short-term (months) exposure conditions is of interest to industry. The present paper reports interim progressive corrosion mass loss results for 5 different specialized low alloy structural steels used in ship construction.
