I am afraid I can only make some general comments on your question given the lack of details and my lack of experience with cathodic/anodic protection systems. The corrosivity of your product containing the sulfuric acid will depend on what other constituents are present. The presence of chlorides or oxidizers at very low levels under acidic conditions can cause corrosion of austenitic stainless steels like 316, especially at the high temperature of your process. You will need to dive into the details and carefully research this further to answer your questions. If you decide on exploring cathodic or anodic protection systems, I encourage to consult an expert in their design. A poorly designed cathodic or anodic protection system can make corrosion worse.
