What is the connection between the magnetic and quality of Security Screen Mesh?

The introduction of Security Screen can be divided into the following three categories.

First: 201 stainless steel, low nickel stainless steel, the amount of chromium is about 10, nickel is about 1%, and some steel mills have less than 1% nickel, so it is not easy to resist corrosion, especially in coastal cities. It is even less resistant to corrosion. It is easy to rust in water and it is not recommended to use it in contact with water! It also belongs to austenitic structure, and its magnetic properties are equivalent to those of 304, which are weak magnetic.

Second: 304 stainless steel Security mesh, standard 304 steel material belongs to the austenitic structure of the molecular structure, there is no magnetic, but in the process of processing, especially the wire surface changes in the surface of the reduction surface during the drawing process, by The most corrosion-resistant austenitic structure becomes a slightly harder, magnetic martensite structure, which also changes during the weaving collision, but the change is minute, so the magnetism is also micromagnetic. There is also a case where the acid resistance is enhanced, the chromium element is added, and the austenite is also changed.

Third, stainless iron, similar to the composition of 201, but he is nickel-free, corrosion resistance is also greatly reduced, commonly known as non-magnetic and nickel-free.
