Mechanical Properties 304 vs 316 stainless steel
These values only apply for thickness less or equal to 1.5 inch 38mm. For thickness above 38mm, 304 tensile strength and yield strength is same with 316, meanwhile 304L is same with 316L, but hardness is different.

Difference between 304/304L and 316/316L Stainless Steel Plates
Both grades are austenitic stainless steel which is one of the most widely used and versatile type of steel. As 304/304L stainless steel plates & sheets have excellent corrosion resistance, 316/316L plates have higher nickel content than 304 and 304L SS sheets giving them even better corrosion resistance especially in marine applications.
Why and How Stainless Steel Plates Resistant to Corrosion
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure major role is chromium (Cr). Chromium has high chemical stability and can form a passivation film on the steel surface to isolate the metal from the outside. To protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. When the passivation film is broken, the corrosion resistance is lowered.
