Low Alloy SS Arc Welding Electrode
E9018-M is an electrode used for welding higher strength steels when tensile strength in excess of 90 ksi is required. The coating on this electrode is specially formulated to resist moisture pick-up in conditions of high heat and humidity. It’s resistance to moisture reabsorption also helps prevent hydrogen cracking and aids in elimination of starting porosity.
Typical Applications : joining HY-90, HY-80, T-1 and other high tensile steels
