Stainless steel products are sturdy and durable, and are a good helper in life. There are many models of stainless steel products on the market, such as: 201, 202, 301, and 304. What is the difference between these numbers? Why is everyone flaunting the 304 stainless steel they use?

Take 201 and 304 as examples. First of all, the difference lies in the alloying elements contained in the material. The proportion of alloying elements contained in 304 steel can be used as food grade and medical grade materials, and the safety performance of daily household use is relatively high.

Secondly, the price gap is huge. The price of 304 material on the market is about twice that of 201 material. Therefore, some unscrupulous merchants use 201 material to pretend to be 304 steel products for sales, and print DUS304 or SVS304 and other irregular 304 marks on them to be shoddy. The SUS304 logo will be printed on regular stainless steel products when they leave the factory.
