Corrosion is the process of stainless steel damage caused by external media. Corrosion is divided into two categories: one is chemical corrosion that is destroyed by chemical reaction between stainless steel and medium, such as high-temperature oxidation of stainless steel, decarburization, corrosion in gas, etc.
Another type is electrochemical corrosion, which is destroyed by electrochemical processes between metals and media. For example, atmospheric corrosion, corrosion in various electrolytes, etc. For stainless steel materials, the most important is electrochemical corrosion.
