Description
Rutile high recovery coated electrode for Alloy 20
Fully austenitic weld metal with high resistance to corrosion in sulphuric acid, mineral acids and organic acids. Typical applications include tanks and vessels, piping, cast pumps, valves, heat exchanger and other components used in chemical processing, metal cleaning and pickling industries. Excellent weldability with a spatter free arc, self-releasing slag producing a very smooth bead appearance. High recovery coating increases deposition rate but limits welding position to flat.
