Corrosion resistance is relative and conditional. The corrosion resistance of stainless steel, which we often talk about, refers to its ability to resist rust and corrosion under certain conditions. Until now, there is no stainless steel that does not rust in any corrosive environment, so the selection of materials should be based on specific application conditions. After selecting the stainless steel trademark, the application part also needs to be correctly applied based on the characteristics of the selected stainless steel, that is, reasonable material selection and correct application are necessary to achieve the intention of stainless steel or corrosion resistance.

Other choices of stainless steel not only need to consider its ability to withstand ordinary corrosion, but also its ability to resist partial corrosion. In some aqueous and chemical media, the latter is even more important. This is because material selection personnel generally pay more attention to the general corrosion resistance of stainless steel, but under general application conditions, their sensitivity to partial corrosion, such as stress corrosion and pitting corrosion, is less considered; Partial corrosion of stainless steel often occurs in corrosive environments with good resistance to general corrosion. Partial corrosion often leads to sudden damage to stainless steel equipment and components, and this hazard is much higher than general corrosion.

Under certain application conditions, there may be situations where even trace amounts of metal ions in certain stainless steels are present in the working medium or industrial products produced, which can still affect the quality of chemical processes and industrial products (including gloss, color, purity, etc.). This is common in industries such as nuclear fuel pharmaceuticals and pigments, where stainless steel that does not contain a certain element or stainless steel with appropriate corrosion resistance levels is generally selected, and then the metal ions are reduced to the acceptable limit.
Salt spray corrosion can damage the passivation film on the surface of stainless steel plates, causing the decorative properties of the plates to be lost and reducing the mechanical strength of the materials; Some electronic components and electrical circuits may experience power line interruptions due to corrosion, especially in environments with vibration, which is particularly severe; Whenever salt spray falls on the surface of the insulator, it will cause a decrease in the surface resistance of the stainless steel plate; After the insulator absorbs the salt solution, its volume resistance will also decrease by four orders of magnitude; The moving parts of mechanical or moving parts are stuck due to the occurrence of corrosive substances and the frictional force of the advancing material.
