201 filter screen and 304 filter screen what are the differences

Stainless steel mesh is stainless steel wire rod, coarse material, after repeated drawing, annealing processing into fine line, and then produced by stainless steel mesh weaving machine. Stainless steel materials are not only capable of air, steam, water and other weak corrosive media, in acid, alkali and salt and other environments also have good corrosion resistance. Stainless steel mesh is also called acid - resistant mesh. Stainless steel filter manufacturers today for us to briefly introduce how the difference 201 stainless steel mesh and 304 stainless steel mesh. Stainless steel mesh can be better rust prevention, because of the amount of chromium and nickel elements. 201 stainless steel and 304 stainless steel difference, to be chromium (Cr), nickel (Ni) content is different. For example, standard 304 stainless steel contains 18 percent chromium and 9 percent nickel. The 201 stainless steel contains 15 % chromium and 5 % nickel. The pitting corrosion resistance of 201 stainless steel is much lower than that of 304, so the rust prevention function is much different. The price is also much different or even double. The market has a lot of 201 stainless steel counterfeit 304 stainless steel, because the naked eye can not see, it is difficult to separate out the real material. I give us a few ways to introduce how to difference 201 stainless steel and 304 stainless steel magnet is a general way, generally can be different. 201 has high magnetic value, 304 has no or slightly weak magnetic value. Potion detection (overview see stainless steel potion detection method, general quality supervision part of the instrument has, you can take a few to test. To measure the content of Ni, 201 generally 0-5 Ni304 has about 9Ni.
