S659929-002 - Hobart SubCOR 100F3-S 3/32" SAW Wire 60lb Coil

Technical Overview of Hobart SubCOR 100F3-S

The Hobart SubCOR 100F3-S is a premium low-alloy composite metal-cored electrode specifically engineered for submerged arc welding (SAW) in high-demand industrial environments. This 3/32-inch diameter wire is formulated to meet the rigorous AWS A5.23 chemistry F3 classification, making it a critical component for fabrication projects requiring exceptional tensile strength. Unlike traditional solid wires, the metal-cored design of the SubCOR 100F3-S allows for higher current densities, resulting in superior deposition rates and improved travel speeds without compromising the mechanical integrity of the weldment.

Designed for use with neutral or active submerged arc fluxes, this electrode excels in producing weld deposits with tensile strengths consistently exceeding 100 ksi (kilopounds per square inch). The composite nature of the wire ensures a consistent chemical composition throughout the length of the coil, providing reliable mechanical properties in both single-pass and multi-pass applications. The formulation is particularly effective for joining high-strength low-alloy (HSLA) steels, where maintaining toughness and preventing cracking is paramount. The wire's chemistry is optimized to deliver robust performance even in challenging conditions, such as those found in sour gas environments.

Industrial applications for the SubCOR 100F3-S are extensive, ranging from the fabrication of heavy-walled pressure vessels to the construction of large-scale storage tanks. Its ability to deposit high-quality weld metal rapidly makes it an efficient choice for the manufacturing of heavy equipment components, such as crane booms, earthmoving machinery frames, and structural supports. The 60lb coil packaging ensures extended run times between changeovers, maximizing arc-on time and operational efficiency in automated or semi-automated SAW setups. By leveraging the advantages of metal-cored technology within the submerged arc process, Hobart provides a solution that balances productivity with the stringent quality requirements of modern high-strength steel fabrication.
