A novel approach for performing electrochemical testing on in-situ stainless steel surfaces is presented. This approach involves the use of an absorbent pad placed on the test surface to facilitate the application of standard electrochemical test methods. A detailed description of the experimental procedure is provided. The test method has the advantages of being nondestructive and can be used as a field test. Examples of the successful use of this approach for the in-situ evaluating the pitting resistance of 316L pharmaceutical tanks and for nondestructive detection of sigma phase in cast duplex stainless steel are provided. Other possible applications and limitations of the test method are discussed.

Key words: In-situ testing, electrochemical testing, stainless steel, pitting resistance, sigma phase

Rare corrosion failures of stainless steel are reviewed in the paper. The cases originate from low chloride waters like potable water or fresh water in the temperature range of 15-25°C. Under such conditions full resistance of austenitic stainless steel like AISI 316 is usually expected.
