Industrial applications crevice corrosion

This type transfers heat from the process liquid to the cooling water across a large number of thinly spaced corrugated plates. They find particular application in food and beverage industry applications or for smaller heat loads in hotels or hospitals. Plate and frame types are widely used because of their compact design and availability of various construction materials. Because localized corrosion and metal wastage can occur within the crevices (crevice... 

With this requirement profile, these steels can also be considered for applications in marine atmosphere or industrial atmospheres. The steels 1.4003 (X2CrNil2) and 1.4512 (X2CrTil2) are not likely to show any corrosion-related cross-sectional reductions, even over periods of several decades, with the exception of highly aggressive conditions. Crevice corrosion can be expected under heavy chloride exposure and in the presence of crevices. Such critical conditions do not result from seawater exposure only, but are also seen inland due to deicing salt, etc. The ferritic chromium steels are not, by the way, formulated with crevice corrosion resistance in mind [100]. 

The excellent crevice corrosion resistance of Beta C, coupled with its excellent elevated-temperature strength, provides a useful combination of properties for industrial applications such as... 

There are large numbers of reported case histories of MIC on stainless steel in water and aqueous waste systems. They are related to different industrial applications such as freshwater storage and circulation systems in nuclear power plants [103, 113,116,142] and cooling water systems in chemical process industries [117,118]. There are basically three cases (a) crevice corrosion under unexpected deposits, (b) sensitivity of pitting and crevice corrosion to trace of H2S, and (c) crevice corrosion in natural seawater. Most of these reports are not well documented concerning the microorganisms involved in the process. However, some general features are...
