S689319-078 - Hobart Fabco 316LT1-1/4 1/16" Stainless Flux-Core Wire 27.5lb

Technical Overview of Hobart Fabco 316LT1-1/4

The Hobart Fabco 316LT1-1/4 is a gas-shielded, flux-cored stainless steel wire designed for high-performance joining of austenitic stainless steels. Classified under AWS A5.22 as E316LT1-1 and E316LT1-4, this consumable offers the versatility to operate effectively with either 100% CO2 or a blend of 75% Argon and 25% CO2. The 1/16-inch (1.6mm) diameter is optimized for higher deposition rates, making it an excellent choice for fabrication of thicker sections where productivity is paramount. The wire deposits a low-carbon molybdenum-bearing austenitic stainless steel weld metal, matching the composition of Type 316L base materials.

Metallurgically, the "L" designation indicates a maximum carbon content of 0.04%, which significantly reduces the risk of sensitization and intergranular corrosion caused by carbide precipitation during the welding process. This makes the Fabco 316LT1-1/4 suitable for applications involving corrosive media or high-temperature service. The flux formulation provides a smooth, stable arc with a spray-like transfer, resulting in minimal spatter and a flat to slightly convex bead profile. The slag system is designed for easy detachment, often self-peeling, which reduces post-weld cleaning time and labor costs.

This wire is engineered for DCEP (Direct Current Electrode Positive) polarity. Mechanical properties of the undiluted weld metal typically include a tensile strength of approximately 85,000 psi (590 MPa) and elongation of 35%, ensuring robust and ductile joints. It is widely utilized in industries such as chemical processing, pulp and paper manufacturing, textile machinery fabrication, and food processing equipment where 316L stainless steel is the standard material. The 27.5 lb spool packaging fits standard industrial wire feeders, ensuring continuity in high-volume production environments.
