Sodium Hypochlorite Effects on 304 SS It is composed mainly of chromium oxide,which prevents further diffusion of oxygen into the base metal.But chromium also is stainless steels Achilles heel.The chloride ion is stainless steels nemesis.The chloride ion combines with chromium in the passive layer,forming soluble chromium chloride. results for this questionWhat happens when chlorine is added to stainless steel?What happens when chlorine is added to stainless steel?Cl2 (chlorine) is a very potent oxidizer (reason it kills bacteria) and therefore high levels of Chlorine may accelerate chloride corrosion of stainless steels.304 and 304L,321 SS may be used for water applications with up to 2 ppm chlorine,while 316 and 316L alloys may take up to 4 ppm.Chloride/Chlorine Levels and Stainless Steel Alloy

It is also found the effect of chloride concentration is reflected qualitatively in the potential (Em) at which the metastable pit or pits start to grow on the surface of Type 304 stainless steel.304 vs 316 Stainless Steel - boulderesBoth are inherently resistant to oxidation (rusting) due to their chromium content that passivates the surface with a chromium oxide layer,but 304SS is more susceptible to corrosion from chloride solutions than 316SS (notably saline environments with high amounts of sodium chloride or salt) due to its lack of molybdenum content.Solutions with as little as 100 ppm of sodium chloride can begin to have a corrosive effect on 304SS
