What is difference between SS 304 and SS 316

Question

Accepted Answer

SS 304 and SS 316 are both stainless steel alloys, but they differ in their composition and properties.

SS 304 contains 18% chromium and 8% nickel, while SS 316 contains 16% chromium, 10% nickel, and 2% molybdenum.
SS 316 has better corrosion resistance than SS 304, especially in environments with chlorides or acids.
SS 316 is more suitable for marine applications or those involving exposure to harsh chemicals.
SS 304 is generally more affordable and widely used in applications where corrosion resistance is not the primary concern.
Both alloys have excellent welding and forming characteristics.
The choice between SS 304 and SS 316 depends on the specific application and the required level of corrosion resistance.
