Paper No. 313 THE CORROSION OF SOME STAINLESS STEELS IN A MARINE MUD. R Francis, G Byrne. Weir Materials & Foundries Park Works Newton Heath Manchester. M402BA U.K. HS Campbell University of Surrey Dept of Materials Science and Engineering Guildford Surrey. GU25XH U.K. ABSTRACT. The report presents the results for three alloys; carbon steel, 316L stainless steel and the authors’ company’s proprietary super duplex stainless steel (UNS S32760)*, exposed in a marine mud off the south coast of England for 5 years. Analysis of the mud showed it to be very aggressive using a corrosion index developed at the University of Manchester. Carbon steel showed a typical corrosion rate for microbial attack with pits up to 0.64mm deep. The316L stainless steel had extensive broad, shallow attack with a few, deeper pits. The Z100 parent pipe and weldments showed no evidence of corrosion attack. Keywords: Marine Corrosion, MIC, Stainless Steel. * The alloy is referred to by the generic name Z100 hereafter.
