SS 316 can tolerate chloride upto 1000 ppm (and some time in running seawater) however; these are when SS 316 is in an oxidizing atmosphere but under reducing conditions such as biofouling/fouling etc chloride tolerance is lower. Most of the cases are those where water has remained stagnant and biofouling has taken place.
