E385-16
Alloy 385 is used for welding materials of similar chemical composition (UNS Number N08904). These materials are used in fabrication of equipment and vessels for handling and storing sulfuric acid and phosphoric acid. The weld metal is fully austenitic and, as such, the low melting constituents such as carbon, silicon, and phosphorus should be kept low. Welding must be done with low heat input, using stringer bead technique.
