Stainless steel wire is simply misunderstood is its title-stainless steel wire. People will think that stainless steel is steel that does not rust, and other stainless steels are steel wires that are not easy to rust;

There are several reasons why stainless steel wire will rust:

1. The stainless steel wire is not easy to rust mainly because the stainless steel wire shows that there is a layer of oxide film to protect the iron element inside the stainless steel wire. The air contact makes the stainless steel wire not easy to rust; when the stainless steel wire is processed, assembled, welded, and welded (Such as flaw detection experiments) and other processes that bring surface oil stains, rust, metal contaminants, welding slag and spatter, etc., and when the stainless steel wire is located in the system, there are corrosive anions (such as Cl-, Br-, When F-halogen ions), these substances simply destroy the oxide film on the surface and reduce the corrosion resistance of the stainless steel wire. The stainless steel wire will corrode and cause other forms of corrosion;

2. The rust resistance of stainless steel wire is related to the anti-corrosion elements contained in the stainless steel wire; such as chromium, nickel, molybdenum and other elements; the more anti-corrosion elements in the stainless steel wire, the better the anti-corrosion and rust resistance of the stainless steel wire; The stainless steel wire with the best corrosion resistance in stock is 316 stainless steel wire, followed by 304 stainless steel wire, and then to 201 stainless steel wire;

Does the stainless steel wire rust after processing? If the other conditions of the stainless steel wire remain unchanged, it will soon rust, then it is time to damage the protective film of the stainless steel wire during processing; in this way, a passivation solution can be used to form a protective film on the surface of the stainless steel wire, or on the surface of the stainless steel wire Electroplating a kind of anti-corrosion element; these two conditions are to increase the protective film of the stainless steel wire and increase the corrosion resistance of the stainless steel wire;
