ROD EXC 9018M MR 1/8X14

PRODUCT DESCRIPTION:

The Lincoln Electric Excalibur 9018M MR Stick (SMAW) Electrode  ED030869 is a premium low-hydrogen, low-alloy stick welding rod engineered for high-strength steels such as ASTM A514, HY-80, and HY-90 and other structural or field fabrication applications. Classified AWS E9018M H4R, this 1/8″ electrode produces weld deposits with at least ~90 ksi tensile strength and good ductility, while its low-hydrogen coating ensures a stable arc with easy slag control and excellent weld quality. Packaged in a hermetically sealed 50 lb can to maintain dryness and performance, it’s designed for AC/DC+ welding in all positions except vertical-down.
