UNS W88904
AWS A5.9
Welding Wire or Rod Used for welding materials of similar chemical composition (Type 904L). Used in fabrication of equipment and vessels for handling and storage of sulfuric acid and phosphoric acid. Weld metal is fully austenitic and must be done with low heat input using a stringer bead technique.
