How to differentiate between 201 and 304 Stainless Steel Welded Wire Mesh

It is difficult for people engaged in building materials to distinguish between 201 and 304 stainless steel. In particular, some bad businessmen use 201 materials to sell 304 materials to customers. This not only causes customers to suffer losses but also breaks the market order. More serious risks may occur. Here are six ways to tell how to distinguish between 201 and 304 stainless steel:

The difference between 304 stainless steel and 201 stainless steel, the chemical formula of 201 is 1Cr17Mn6Ni5, the chemical formula of 304 is 06Cr19Ni10; the main difference between them is nickel-chromium element, 304 is 19 chromium 10 nickel, and 201 is 17 chromium 5 nickel

Second, because of the different nickel content, the corrosion resistance of 201 is far less than that of 304; the acid and alkali resistance 201 is not as good as 304; because the carbon content of 201 is higher than 304, so 201 is harder than 304, 304 Better toughness, scratching the surface of 201 with a hard knives will generally have obvious scratches, scratches on 304 will not be obvious

Third, 201 stainless steel contains manganese, but 304 does not; therefore, in terms of color, 201 stainless steel because the color of manganese is darker than 304, 304 is white, but this is not easily distinguishable by the naked eye.

Fourth, because 201 contains manganese, it will rust in the humid and high salt air for a long time, and 304 will not rust; but many people say that 304 is rusted, it may not be 304 at all, don't look at the material. Printed with the standard of 304

The difference between 304 stainless steel and 201 stainless steel, fifth, there is a stainless steel detection syrup on the market, as long as a few drops can be used to distinguish the stainless steel in a few seconds, this syrup is particularly convenient, the principle is to make the material inside The element contains a chemical reaction with the substance in the identified syrup to produce a colored substance. This method is very convenient and accurate and feasible. Currently, the identification syrup can be purchased online, which is difficult to buy on the market.
