Multiple crevice assemblies (MCAs) have been used for over a dozen years to assess the crevice corrosion resistance of stainless-type alloys in seawater and other chloride-containing environments. This paper provides a review of the technique's development, modification, and present usage and discusses its limitations. Results of comparative round-robin testing and other seawater crevice corrosion studies provide perspectives on reproducibility. Insight from established corrosion mechanisms and modelling help to explain variability for some materials. Several examples of alloy rankings and beneficial effects of alloy composition determined by MCA tests are discussed.
