The Difference Between 304 and 316

The difference between 304 and 316 stainless steel

1, 304 stainless steel

First of all, our family commonly used POTS and pans, and daily drinking cups, tableware and so on are made of 304 stainless steel, that is, food equipment, which is widely used.

Daily food design is at most contact with acid and alkali more, the biggest advantage of 304 stainless steel is acid and alkali resistance, and the density is high, polishing without bubbles.

2, 316 stainless steel

316 stainless steel use of food equipment is a little luxurious, but its function is better than 304, generally mainly common in medical, food, machinery, oil and so on,

And 316 stainless steel in some mechanical equipment parts commonly used.

3. How to distinguish

316 stainless steel contains molybdenum (Mo), corrosion is better than 304 stainless steel, generally in the high temperature environment, mechanical engineers use 316 materials to do parts.
The different grades of 304 and 316 are: the grades of 304 are 0Cr18Ni9, and the grades of 316 are 0Cr17Ni12Mo2. If you want to know more about them, you can search directly (the grades of 304 and 316, as well as the chemical composition).
316 stainless steel is mainly to reduce the content of chromium (Cr) to increase the content of nickel (Ni), and increase the content of Mo2%~3%.
Summary: 316 is more than 304 two kinds of elements Ni and Cr, and 316 oxidation resistance is better than 304, and 316 than 304 hardness is high, high rust prevention requirements of products, choose 316 stainless steel, rust prevention requirements are not high products choose 304.
