When we say stainless steel, we don't mean that it will never rust, but that it has good corrosion resistance. Stainless steel models 304 and 3 16 are not easy to rust. In our life, model 304 is more common. This type of stainless steel can withstand the high temperature of 800 degrees. The highest temperature of hot water we usually drink is 100 degrees Celsius, and the temperature of some vegetables is even lower, so 304 is enough, and 3 16 is a stainless steel brand marked by the United States. This standard stainless steel is mainly used in some medical instruments. For some things, when the standard of stainless steel is higher, 3 16 stainless steel will be used. 3 16 stainless steel is not only better than 304 in corrosion resistance, but also better in hardness and oxidation resistance.
It can also be seen from the price that the price of 3 16 stainless steel products in the market is higher than 304. This is because there are two more elements in the material of 3 16 stainless steel. Whether 304 or 3 16 is better depends on our own needs, although 3 16 may be better than 304 on the whole. However, it is ok to use 304 materials for some basic things in our life. 3 16 is more suitable for some large and exquisite things, such as instruments and so on. 304 is more suitable for entering thousands of households and has a wider audience.
So which stainless steel is better, 304 or 3 16, depends on their uses.
