255111825 - ESAB Atom Arc T E11018M Low Alloy Stick Electrode 1/8 Inch

High-Performance Electrodes for T-1 Steel Applications

The ESAB Atom Arc T Stick Electrode is a premium low-hydrogen, low-alloy consumable engineered specifically for the welding of T-1 (ASTM A514) quenched and tempered steels. With an AWS classification of E11018M H4R, this electrode is designed to produce weld deposits that match or exceed the mechanical properties of the base metal, ensuring 100% design joint efficiency in both as-welded and stress-relieved conditions. This makes it an essential component for critical structural applications where high yield strength and ductility are paramount.

Metallurgically, Atom Arc T offers exceptional performance with a tensile strength ranging from 112 to 115 ksi. The "M" designator in its classification indicates compliance with rigorous military specifications, ensuring superior toughness and crack resistance. The H4R suffix denotes a moisture-resistant coating that limits diffusible hydrogen to less than 4ml per 100g of weld metal, significantly reducing the risk of hydrogen-induced cracking (cold cracking) which is a critical concern when welding high-strength low-alloy (HSLA) steels.

This product comes in a 4.54 kg (10 lb) hermetically sealed steel carton, which provides optimal protection against atmospheric moisture absorption during storage and transport. It carries a comprehensive suite of certifications, including ASME SFA 5.5, AWS A5.5, ABS, CWB, CSA W48, and MIL-11018-M, validating its suitability for regulated industries such as bridge construction, shipbuilding, and heavy civil engineering. The 1/8-inch diameter allows for an operating amperage range of 90 to 160 Amps, providing versatility across various joint configurations and plate thicknesses.
