Description
E9018-B3L is an outstanding electrode for welding high strength piping, where cracking is a problem. The E9018-B3L provides excellent notch toughness, 20 ft•lbs minimum at 100°F. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. The electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity.
