Feb 14, 2020 · Common stainless steels. The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum. 304 stainless steel does not. 304 vs 316 Stainless Steel, What is the difference?Sep 24, 2020 · On the other hand, 304 types have a melting point higher than type 316 (50 to 100 °F higher than 316 types). 304 type is commonly used for residential appliances and indoor architectural hardware. Type 304 is better for the applications where chlorinated solutions are not a concern as it is less expensive than type 316.
Nov 21, 2019 · Properly passivated type 304 stainless steel should be excellent in a non-salty, non-chlorine environment as long as it is not in metallic contact with any other metal. If it actually is in contact with or splashed with salt water, 304 SS is unlikely to be acceptable, you'll probably want 316 SS. Please explain your application. Thanks. Good luck.

How can I tell if my stainless steel is 304 or 316? Whats the difference between 304 and 316 stainless steel? 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). What Is The Difference Between 304 And 316 Stainless Steel 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. The differing chemical makeups of 304 SS and 316 SS influence how each performs in a certain environment.How to Test if your Stainless Steel is Grade 304 or 316 Wire?Jun 09, 2015 · Acid testing is one test that will separate 304 and 316 grades of stainless steel. Sulphuric acid strongly attacks 304 grade, producing green crystals and a dark surface, but its attack on 316 grade is slow and produces a brown surface Hydrochloric acid attacks 304 grade very rapidly and produces gas, but attacks 316 grade only very slowly.
