S280343-002 - Hobart SubCOR 120-S 1/8" Metal-Cored SAW Wire, 60lb Coil

High-Performance Composite Electrode for Submerged Arc Welding

The Hobart SubCOR 120-S is a premium low-alloy composite metal-cored wire electrode engineered specifically for submerged arc welding (SAW) in high-strength industrial applications. Unlike traditional solid wires, the SubCOR 120-S features a metallic sheath filled with a precise formulation of metal powders. This composite design allows for higher current densities and significantly improved deposition rates, making it a highly efficient choice for heavy fabrication environments where throughput and weld quality are critical.

Designed to meet the rigorous chemical requirements of AWS A5.23 M4, this electrode is formulated to produce weld deposits with tensile strengths exceeding 110,000 psi (110 ksi). This makes it an exceptional solution for welding High-Strength Low-Alloy (HSLA) steels and Quench and Tempered (Q&T) steels, which are commonly found in the manufacturing of heavy equipment, cranes, and pressure vessels. The wire's chemistry is balanced to ensure consistent mechanical properties, including excellent impact toughness, even in demanding service conditions.

The SubCOR 120-S is versatile enough for both single and multiple pass applications when paired with the recommended submerged arc flux. Its ability to maintain arc stability and produce smooth bead profiles reduces the need for post-weld rework. By utilizing a metal-cored design within the submerged arc process, fabricators can achieve deeper penetration profiles and better side-wall fusion compared to some solid wire alternatives. This 60lb coil configuration is designed for standard industrial wire feeders, providing a balance between run-time duration and ease of handling during changeovers.

Industries such as power generation, shipbuilding, and structural bridge fabrication rely on the SubCOR 120-S for its reliability and high-performance characteristics. Whether joining thick sections of cast steel or fabricating critical structural components, this electrode delivers the metallurgical integrity required for safety-critical welds.
