Information
The basic knowledge of that much stainless steel was introduced earlier. I know that there are many benefits of stainless steel. Stainless steel products can be seen everywhere in our Foshan city, stainless steel railings, stainless steel bathroom, stainless steel tableware and so on. So many products are closely related to the safety of our lives and property, we can see that stainless steel is so important.

There are so many series of stainless steel products, and they must be divided into different categories. The stainless steel market is so big and profitable will surely lead to stealing. If the bad guys around the masses give us a shoddy good, then we honest and good people will not be lost. Good people must learn to use scientific methods to fight against criminals, so how do we distinguish the true and false of stainless steel? Today, the editor will teach us the fundamental way to distinguish. Take various tube types for stainless steel railings as an example. The most commonly used method of stealing posts for occupations is to use 201 instead of 304, and 304 instead of 316.

Generally, we will hear about the use of magnets to detect stainless steel. Those who do not attract are considered to be real and those who attract are considered counterfeit. This is a very one-sided method. To answer this question, you must first understand a few terms: austenite, martensite, and ferrite. Is it very professional? If you don't understand, we just need to remember that austenite is not magnetic or weakly magnetic, and 304, 316 are all austenitic stainless steels, and other bodies are magnetic. The original principle of using magnets to detect stainless steel comes from this. But 410, 420, 430 are all attributed to martensite or ferrite. It is embarrassing to look at it this way. In addition, after austenitic stainless steel undergoes cold deformation treatment, the crystal phase will change and become magnetic. If you want to restore the austenite crystal phase, a quenching process is required. The magnetic identification method is not completely scientific, but it can be used as a preliminary judgment of 304 and 316. Some have been tested by stainless steel testing reagents, but they cannot accurately distinguish the types. If you want to get a certain type of stainless steel properly, it is the most accurate and reliable to go through a professional testing organization.
