I had a stomachache after eating takeout some time ago, and I plan to buy an insulated lunch box to cook for myself. I looked at the lunch box online. There are two kinds of stainless steel, 3 16 and 304, but I don't know which is better, so I did my homework. Generally speaking, the quality of 3 16 stainless steel is slightly better than that of 304 stainless steel.

3 16 stainless steel is better. 3 16 stainless steel is superior to 304 in corrosion resistance, hardness and oxidation resistance. Because 3 16 stainless steel is doped with molybdenum on the basis of 304, molybdenum can better consolidate the molecular structure of stainless steel, make it more wear-resistant and oxidation-resistant, and improve its corrosion resistance.

But it should be noted that the price of 3 16 is much higher than that of 304. 3 16 stainless steel is a rare metal, so 3 16 stainless steel is more expensive. 3 16 is more convenient to use than 304. On the one hand, it has strong corrosion resistance, on the other hand, it is particularly strong. Most of the instruments seen in the factory are made of this stainless steel.
