Which is better SS 304 or SS 316?

Which is better SS 304 or SS 316?

For instance, 316 stainless steel is more resistant than 304 to salt and other corrosives. So, if you are manufacturing a product that will often face exposure to chemicals or a marine environment, 316 is the better choice.

What is the difference between SS 304 and 316?

The simple answer is 304 contains 18% chromium and 8% nickel while 316 contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).

How do you tell a 304 from a 316?

Aesthetically, there is no difference between the two; in fact, the only way to differentiate between them is to test them chemically. The main difference between 304 and 316 stainless steel is 316 SS has the addition of molybdenum.

What is the best stainless steel for marine use?

SAE 316 stainless steel
SAE 316 stainless steel is a molybdenum-alloyed steel and the second most common austenitic stainless steel (after grade 304). It is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than most other grades of steel without molybdenum.

Is 316 stainless good for saltwater?

5) The traditional ferritic and austenitic stainless steels (including types 304 and 316) are unsuitable for use in seawater because they are prone to crevice corrosion and pitting attack, giving rise to a high probability of premature failure.

Is 316 stainless steel a marine grade?

316 grade steel is often known as Marine Grade Stainless Steel and is one of the most common stainless steel on the market. It is an austenitic grade that has also 2-3% molybdenum, further enhancing corrosion resistance.

Is 316L stainless steel good for sea water?

316L stainless steel is a popular choice for seawater filtration. This is in part due to the alloy’s widespread use throughout many industries, making it widely available, as well as the benefits described below.
