About SS Flanges

Stainless steel (SS) flanges are typically manufactured from austenitic stainless steel alloys most commonly grades304 and316 whose corrosion resistance and mechanical properties derive from their precise chemical compositions. Below is a summary of the key alloying elements and their typical weight percent ranges for these two grades:

Notes:

Grade304 ("18/8 stainless steel) is the most widely used SS flange material, valued for its general purpose corrosion resistance and formability .
Grade316 adds molybdenum for enhanced resistance to chlorides and marine environments, making it preferable for more aggressive service conditions
Minor elements (P, S, Si, Mn, N) are controlled to low maximum levels to optimize corrosion resistance and weldability.
