Topic: Re: Salinity endurance of stainless steel

posed by 
From the little information given, I would be concerned with pitting corrosion of the 316L stainless steel in the presence of the chlorides. The user does not mention other important considerations like temperature, degree of aeration, time of exposure, etc. In general, higher temperatures and the presence of oxygen (air) will make things worse from a corrosion standpoint. Stainless steel alloys with a higher molybdenum content, such as a duplex stainless steel like 2205 or a superaustenitic like AL6XN, would be better choices.
