Español1. 304 stainless steel belongs to the sub-stable stainless steel. After returning the goods, it belongs to the state of single austenite structure, without magnetism, but after cold working deformation, such as stamping, stretching, etc., some austenite structures will produce normal photos. It turns into martensite again, and it is magnetic. The strength of the magnetism varies according to the amount of deformation. Under normal circumstances, it will not be attracted by the magnet at all.
2. The use of stainless steel materials in our country is relatively short, and there are certain misunderstandings about stainless steel among consumers in general, especially the way of changing the magnetic properties is itself a misunderstanding.
Due to the existence of this kind of knowledge, many merchants use similar 200 series model materials with poor corrosion resistance, non-magnetic or weak magnetic to process products, and consider the same effect as 304 from the perspective of speech, and then there are many types of stainless steel, which need to be verified Not in this way but with some instruments.
3. In addition, martensitic stainless steel is rarely used in sinks, mainly in the tool industry. There is another kind of ferritic stainless steel, which belongs to magnetic stainless steel. It has a wide range of uses and is also used in the sink industry. I won't go into details here.
But in terms of cost, at present, the cost of stainless steel is the highest for the main stream 304 used in the sink, so you can see if it is stainless steel instead of stainless steel.
