201 stainless steel wire is a kind of common steel wire and also a kind of stainless steel wire widely used. We all know that in some environments, the damage caused by chemical or electrochemical interaction between metal and surrounding medium is called corrosion. 201 Stainless steel wire is also a kind of metal wire, so it will also be corroded. Today we will introduce the corrosion environment and corrosion method of 201 stainless steel wire:

1. 201 Stainless steel wire can be divided into chemical corrosion and electrochemical corrosion according to the nature of action.

2. 201 Stainless steel wire can be divided into general corrosion according to corrosion form. General corrosion, such as pitting corrosion, crevice corrosion, stress corrosion, corrosion fatigue, selective corrosion and erosion corrosion, is distributed on the whole stainless steel surface.

3. 201 Stainless steel wire can be divided into industrial water corrosion, soil corrosion, acid, alkali and salt corrosion, seawater corrosion, high temperature corrosion (including liquid metal, molten salt and gas corrosion) according to the environment and conditions where corrosion occurs.

In order to improve the corrosion resistance of 201 stainless steel wire, some treatments, such as polishing, galvanizing, and plastic spraying, are generally carried out on the stainless steel wire to improve the corrosion resistance and other properties of 201 stainless steel wire.
