The Role of Marine Bacteria in Stainless Steel Pitting

Abstract

Flat plate and welded stainless steel coupons (316L, Nitronic 50 an AL6xN) were evaluated for potential microbiologically influenced corrosion in seawater. No pitting was observed in flat plate of welded AL6xN under the exposure condition after one year. Pits were located at welds of Nitronic 50 and 316L stainless steels after six- and eight-week exposures. In all cases, large numbers of bacteria were associated with the corrosion products. No corrosion was located on flat plate coupons of 316L or Nitronic 50.
