Chloride induced pitting corrosion is a known issue with austenitic stainless steel alloys such as 304 and 316. Alloy 316 is somewhat more resistant to the initiation of chloride-induced pitting than is alloy 304, but not fully resistant. Pitting corrosion is a localized form of galvanic corrosion. It is initiated at a local imperfection in the

GALVANIC CORROSION Galvanic corrosion occurs when at least two metals are connected and one metal corrodes (anode) in preference to another (cathode). Corrosion can often be attributed to the poor compatibility of selected materials where one metal corrodes in preference to another, creating a anodic-cathodic cell.

Protection leads to pipes (steel or cast iron), tanks and structures. Cadweld connections weld the conductors and the structure to be protected so no galvanic corrosion can occur at the interface. The Cadweld process is specifically formulated to provide minimum heat effect on steel, which is especially important on thin-wall, high-stress pipes.
