Many people may have such doubts, is stainless steel magnetic or not? Some people also think that stainless steel is not magnetic. If you use a magnet to attract a stainless steel plate, it is considered to be a counterfeit product with magnetism. In fact, there are many types of stainless steel plates. Whether it is magnetic or not depends on the specific material. The following is a brief analysis. HLL cold rolled aisi 306 stainless steel coil magnetic problem.
Generally speaking, stainless steel can be divided into the following two categories according to the organizational structure:
A. Martensite/ferrite: such as 410, 420, 430, etc.;
B. Austenite: such as 304, 310, 316, 321, etc.;
Among them, martensite/ferrite is magnetic, while austenite is generally non-magnetic or weakly magnetic. Austenitic HLL cold rolled aisi 306 stainless steel coil is basically non-magnetic or weakly magnetic, but due to the production and smelting process, advantages or fluctuations during processing, it may cause some magnetic properties, but this It does not mean that it is a substandard product or counterfeit.
In addition, HLL cold rolled aisi 306 stainless steel coil is cold-worked during processing, so its structure contains a certain amount of martensite, and martensite is magnetic, which leads to HLL cold rolled aisi 306 stainless steel The coil has a certain degree of magnetism. The greater the degree of parallelism during processing, the more martensite contained in the material, and the greater the magnetism.
Is there a way to eliminate the magnetism on the HLL cold rolled aisi 306 stainless steel coil material? This can be solved from the processing process. Since it is magnetized mainly due to processing deformation, the material can be restored to Austria through warm solid solution. Tensite structure, so that it can play the role of demagnetization.
However, when consumers buy HLL cold rolled aisi 306 stainless steel coil, it is not necessary to judge the quality by whether the material is magnetic, because there is a certain amount of magnetism in the production process of HLL cold rolled aisi 306 stainless steel coil. normal.
