I was wondering which Stainless Steel Metal would be the for a pure salt water mixture? It is a square tank that the solution is being placed into. Hot much would the temp effect the material??%7D>

Most of the 300-series stainless steels are not appropriate for use in salt water unless constant velocities are maintained. For long term service, I suggest one of the super austenitics, i.e., AL6XN or similar. Temperature has a significant effect on the corrosion of stainless steel in seawater with increasing rates with increasing temperatures. Hope this helps! David Hendrix The Hendrix Group Inc.

tjc, Are you sure that a "stainless steel" tank is absolutely necessary ? Could FRP or PVC be another choice ? These would be good choices as long as the temperature was not too high.....(about 150-175F for most FRP and about 120F for PVC and CPVC) When you get into the "super austenitics" and duplex stainless steels, you are getting intoa lot of money... The fact that you are considering a rectangular tank makes me hope that it is a low pressure application.... More details ??? MJC
