Investigating Vulnerable Systems and Components

More often than not, a large percentage of the risk ( 80%) is found to be associated with a small percentage of the equipment item ( 20%) [6], In other words, there are certain components in a system that could be vulnerable to MIC, and also certain types of materials which are prone to a risk of biocorrosion. 

Therefore, for example, the possibility of getting MIC in the power generation industry is high, and in this particular industry, cooling systems are more susceptible to MIC than, say, the fire-side of the water walls in the boiler. 

Moreover, it must also be noted that different classes of stainless steels do not behave the same when exposed to biological environments. For instance, apparently, grade 304 stainless steel may be regarded as inferior to grade 316 stainless steel from the standpoint of resistance to MIC.
