The EMA Series Stainless Steel is 304 SS not 316 SS

What’s 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) https://www.nemaenclosures.com/blog/304-and-316-stainless-steel/
