People often think that magnet adsorption stainless steel wire to verify its advantages and disadvantages and authenticity, no magnetic absorption, is considered to be good, genuine; Suction is magnetic, so think it is counterfeit, fake. Originally, this is a kind of extremely one-sided, fault distinction method. In fact, stainless steel wire will “rust”, also can take magnetic stainless steel wire is beyond 60% of the iron as the matrix, to participate in the high alloy steel such as copper, nickel, molybdenum and other alloy elements, its biggest characteristic is corrosion resistance ability is stronger, but stainless steel wire is not absolutely rust. In coastal areas or some serious air pollution places, when the content of chlorine ions in the air is large, exposed to the surface of stainless steel wire in the atmosphere can have some rust spots, but these rust spots are limited to the surface, will not corrode the internal matrix of stainless steel wire.

The breed of stainless steel wire is a lot of, most contain magnetism, consequently, absorb with magnet is not the scientific method that discern stainless steel wire. Most of the stainless steel wire that uses as adornment tube board normally is the 304 material that austenite body type pledges material, will tell commonly be to do not have magnetism or weak magnetism, but because smelting causes chemical composition fluctuation or processing state to differ also may appear magnetism, but this cannot think is bogus or unqualified, what reason is this?

The above mentioned austenite is non-magnetic or weak magnetic, and martensite or ferrite is magnetic, due to composition segregation or improper heat treatment during smelting, will cause a small amount of martensite or ferrite structure in the 304 stainless steel austenite wire. In this way, 304 stainless steel wire will have a weak magnetic.

In addition, 304 stainless steel wire through cold processing, organizational structure will also be transformed to martensite, cold processing deformation degree is larger, martensite transformation is more, the magnetic steel is larger. Like a batch of steel belt, producing φ 76 tubes, no significant magnetic sensation; Production φ 9.5 tube, because of the large deformation of ling bending magnetic sense is significant; Due to the larger deformation of rectangular tube than round tube, especially some folding Angle, the more severe deformation and more significant magnetic.
