Analysis of crevice corrosion on stainless steel and detecting its working method or modelling techniques is a part of the Na-hypochlorite solution. Corrosion considering burning products declared by heat burners. This study is an external potential application of 0 mV to +400 mV. This is a process for 316 stainless steel and 304 stainless steels. This research study will help to understand the methodology of the crevice corrosion process, how it works, what the method or techniques are following, and the result of the process corrosion.
