In a corrosive environment, the damage of the metal and the surrounding medium due to chemical or electrochemical action is called corrosion. In a corrosive environment, when the stainless steel is not selected properly, corrosion will also occur. Corrosion is classified as follows:
1. Stainless steel nuts can be divided into chemical corrosion and electrochemical corrosion according to the nature of the action.
2. Stainless steel nuts can be divided into general (comprehensive, uniform) corrosion according to the form of corrosion. The so-called general corrosion, the corrosion of stainless steel nuts is distributed on the entire stainless steel surface, 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 of corrosion, stainless steel nuts 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. .
