ED032602 - Excalibur 9018M MR 1/8" Stick Electrode (50lb Can)

High-Performance Low Alloy Stick Electrode

The Lincoln Electric Excalibur® 9018M MR® (SKU: ED032602) is a premium low-hydrogen stick electrode designed for critical welding applications requiring high tensile strength. Engineered to meet AWS E9018-M H4R specifications, this 1/8-inch (3.2mm) electrode delivers a minimum tensile strength of 90,000 psi (620 MPa), making it the preferred choice for structural fabrication, pressure vessels, and military equipment where standard 7018 electrodes are insufficient.

One of the defining characteristics of the Excalibur line is its moisture-resistant (MR) coating. The H4R designation indicates that the electrode resists moisture pick-up in high-humidity environments, significantly reducing the risk of hydrogen-induced cracking. This feature is vital for field erection and shipyard environments where climate control is difficult to maintain. The electrode is formulated with a low-alloy composition that ensures excellent impact toughness even at low temperatures, meeting rigorous industry standards for safety and durability.

Operational efficiency is maximized through Lincoln's advanced coating technology, which promotes a square burn-off. This allows for better visibility of the weld pool and precise arc control. The slag system is designed to be self-peeling or easily removable, reducing post-weld cleanup time and labor costs. Packaged in a durable 50 lb Easy Open Can, these electrodes are protected during transport and storage, ensuring they arrive ready for immediate use in high-stakes industrial projects.
