Lincoln Excalibur 11018M MR is an AWS A5.5 E11018-M H4R low-hydrogen iron-powder basic-coated moisture-resistant SMAW electrode with 110 ksi minimum tensile, engineered for HSLA, high-strength quenched-and-tempered, and HY-80/HY-100 steels in military, naval, offshore, and pressure-vessel fabrication. The H4R designation delivers up to 60% less moisture pickup than competitive E11018-M electrodes, sharply reducing hydrogen-induced cracking risk on the high-restraint joints typical of high-strength steel work. Runs DC+ in all positions.
