In a corrosive environment, the damage caused by chemical or electrochemical action between metal and surrounding medium is called corrosion. In a corrosive environment, when the stainless steel pipe is not selected properly, 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 refers to the distribution of corrosion on the entire surface of stainless steel. The so-called local corrosion pitting corrosion, crevice corrosion, stress corrosion, corrosion fatigue, selective corrosion, erosion corrosion, etc.
3. According to the environment and conditions where corrosion occurs, it can be divided into atmospheric corrosion, industrial water corrosion, soil corrosion, acid, alkali, salt corrosion, seawater corrosion, high-temperature corrosion, (including liquid metal, molten salt, gas corrosion), etc.
