What is the difference between 304 stainless steel and 316 stainless steel

1, the chemical composition is different: 304 does not add molybdenum, and 316 has molybdenum.

2, corrosion resistance is different: 304 contains only 9% nickel, while 316 contains 12% nickel, so 304 corrosion resistance and other aspects are worse.

3, different performance: 304 corrosion resistance, acid resistance, alkali resistance and other aspects are better, and 316 due to the addition of molybdenum, so the chloride corrosion resistance, heat 

resistance is better.

4, the scope of application is different: 304 is widely used to make POTS and pans, etc., while 316 is widely used in the food industry, medical industry, watch industry, etc.

5, the price is different: Because 316 belongs to food grade, corrosion resistance is better, so the price of 316 will be more expensive than 304.

Second, 304 stainless steel and 316 stainless steel tableware how to distinguish

1, with the naked eye to see 304 and 316 stainless steel, generally can not see the difference, so many businesses for their own interests, 304 stainless steel as 316 to sell, but the price difference 

between the two is quite large, because 316 belongs to the food grade, corrosion resistance is better, so the price of 316 will be more expensive than 304. If you spend 316 money, but buy back 304 

stainless steel tableware, it means that you have spent money.

2, because the chemical composition of 304 and 316 is different, so when distinguishing the two, you can also use professional stainless steel liquid to distinguish. After the liquid is dropped on the 

stainless steel, the surface of the 304 material is generally a little red, and the 316 material will be black.

3, if there is no professional potion, you can also use magnets to test the difference, if the stainless steel belongs to 304 material, it can not be attracted by the magnet. However, the accuracy of this 

method is relatively low.

4, in fact, if it is only for home use, it is not necessary to choose 316 material, because the characteristics of 304 are also fully in line with household standards, so that you can avoid using 316 material

 to buy only 304 products.
