DESCRIPTION: Submerged Arc Cored Wires Low-Alloy Steel CATEGORY: AWS A5.23: ECM4 Submerged Arc Solid Wire is a low-alloy composite metal-cored wire electrode for submerged arc welding in high strength applications. AWS A5.23: ECM4 meets AWS A5.23 chemistry M4, and is designed for tensile strength levels above 110 ksi. MAIN APPLICATION: Single and multiple pass applications with the recommended submerged arc flux, High-Strength Low-Alloy steels, Quench & Tempered steels, Heavy equipment components, structural components, ship hulls, cast steels, boiler & pressure vessels HSLA and Q&T steels Structural fabrication Jack-up rig fabrication Heavy equipment frames Crane beams FEATURES: Metal-cored wire can offer improved deposition rates compared to solid wires at comparable amperages Metal-cored wires offer broader penetrationprofiles compared to solid wires at comparablewelding parameters Very high strength deposit with excellent low- temperature toughness in the as-welded Condition Weld deposit chemistry requirements are identical to those of EM4 solid wires AWS CLASSIFICATIONS:
