In a corrosive environment, the damage caused by chemical or electrochemical interactions between metal and surrounding media is called corrosion. In a corrosive environment, when stainless steel is improperly selected, corrosion will also occur. There are many classification methods for corrosion.
1. According to the nature of the action, it can be divided into chemical corrosion and electrochemical corrosion.
2. According to the form of corrosion, it can be divided into general (comprehensive, uniform) corrosion. The so-called general corrosion means that corrosion is distributed on the entire surface of stainless steel. The so-called local corrosion pitting corrosion, crevice corrosion, stress corrosion, corrosion fatigue, and selective corrosion. Erosion, corrosion, etc.
3. According to the environment and conditions in which corrosion occurs, it can be divided into atmospheric corrosion, industrial water corrosion, soil corrosion, acid, alkali, and salt corrosion, seawater corrosion, high-temperature corrosion (including liquid metal, molten salt, gas corrosion), etc.
