摘要: The water storage tanks of hotel trains suffered pitting corrosion. To identify the cause, were subjected to a detailed metallographic study and chemical composition austenitic stainless steels used in their construction was determined. Both tank corrosion products further examined by physicochemical microbiological testing. Corrosion shown be related an incompatibility between chloride content base filler metals tanks. These findings formed basis recommendations aimed at prevention control such
