E7018 is an AWS A5.1 low-hydrogen iron-powder basic-coated SMAW electrode with 70 ksi minimum tensile strength. It runs on DC+ or AC in all positions and is the workhorse code-quality stick electrode for structural steel, pressure vessel, pipe, and shipbuilding fabrication. The low-hydrogen coating must be kept dry: opened rods exposed beyond 4 hours typically require rebaking at 500-800 F to restore full code performance per AWS D1.1.
