321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridges, automobiles and other industries. However, the "stainlessness" of stainless steel is not absolute. Due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, temperature, etc. will have a greater impact on the corrosion resistance of stainless steel. For example, if stainless steel is used for a long time in the sensitization temperature range of 450~850°C, intergranular corrosion will occur. The mechanism is that C combines with Cr at the grain boundary to form Cr23C6 and precipitate, reducing the Cr content at the grain boundary. This is the so-called "chromium deficiency". The Cr element is one of the main elements that inhibits intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.
