"choice between 304 and 316 SS"

Question:

"We have always a doubt about the choice of type of SS for waste water (municipal, leachate, industry). Usually the concentration in chloride is around 1 to 5 mg/l. When there is no particular ion like iron, what would be the limit between 304/304L 316/316L? We usually do not passivate."

Answer:

With your described water environment, I would expect 304SS and 316S to behave similarly.
