What are the 201 and 304 in the stainless steel table foot?

Have you noticed that the words "201 stainless steel" and "304 stainless steel" are often encountered when purchasing stainless steel table feet? 201 and 304 are two types of stainless steel sheets, but 304 stainless steel and 201 stainless steel are almost indistinguishable with the naked eye come out. In fact, the composition is different. 304 is imported stainless steel plate, which is better in quality, but expensive; while 201 is domestic stainless steel plate, and the quality is slightly worse.


The material of stainless steel table feet is usually 201 stainless steel and 304 stainless steel. What's the difference between the two besides the ingredients?


201 is high in manganese, the surface is very bright with dark and bright, and the high manganese content is easy to rust. 304 contains more chromium, the surface is matte, and it is not easy to rust. The biggest difference between 201 and 304 is the difference in corrosion resistance. The corrosion resistance of 201 is very poor, so the price will be much cheaper, but the corrosion resistance is not as good as 304.


The material price of 304 stainless steel is almost twice as expensive as that of 201, but the rust resistance and acid and alkali resistance are much higher. But relatively speaking, the hardness of 201 is higher than that of 304. When purchasing stainless steel table feet, if it is a household or small-scale one, it is better to choose 304; if you consider the cost of production products, you can choose 201.
