S289619-027 - Hobart Fabcor Edge D2 1/16" Metal-Cored Wire, 50lb Spool

Technical Specification and Alloy Composition

The Hobart Fabcor Edge D2 is a premium low-alloy metal-cored wire engineered for the fabrication of mild and high-strength low-alloy steels. This product is formulated to meet AWS E90C-D2 classifications, delivering a weld deposit containing approximately 0.5% Molybdenum. The addition of Molybdenum significantly enhances the high-temperature strength and creep resistance of the weld metal, making it an ideal choice for demanding industrial applications where structural integrity is paramount. The wire is manufactured to a 1/16-inch (1.6mm) diameter and supplied in a 50-pound spool, suitable for industrial wire feeders and automated systems.

Technically, the Fabcor Edge D2 excels in deposition efficiency compared to solid wires and conventional flux-cored equivalents. As a metal-cored consumable, the composite fill allows for higher current densities, resulting in faster travel speeds and increased deposition rates. The wire is designed to operate with specific shielding gas mixtures to optimize arc stability and mechanical properties. It requires either a mixture of 75-95% Argon with a balance of Carbon Dioxide or a mixture of 95-98% Argon with a balance of Oxygen. These gas blends ensure a spray transfer mode that minimizes spatter and maximizes penetration profile.

The metallurgical properties of the weld deposit are tailored for industries requiring robust mechanical performance. The manganese-molybdenum alloy system provides tensile strengths typically exceeding 90,000 psi (depending on heat input and cooling rates), matching the requirements of high-strength steels used in pressure vessels and heavy structural components. The wire is suitable for both single and multiple pass welding operations in the flat and horizontal positions, offering versatility in fabrication workflows. Storage and handling should follow standard low-hydrogen practices to maintain the integrity of the fill material and prevent porosity.
