ED019589 - Lincolnweld 860 Neutral SAW Flux 50lb

Technical Overview of Lincolnweld 860 Flux

The Lincoln Electric Lincolnweld® 860® is a premium submerged arc welding (SAW) flux designed to meet the rigorous demands of industrial fabrication. As a neutral flux, it offers a balanced chemical composition that does not significantly alter the alloy content of the weld metal based on arc voltage variations. This characteristic makes it an exceptional choice for multi-pass welding applications where consistent mechanical properties are critical throughout the joint depth. The flux is formulated to provide excellent operating characteristics, ensuring stable arc performance and superior slag detachability.

One of the defining technical attributes of Lincolnweld 860 is its ability to produce weld deposits with high impact toughness. When paired with Lincolnweld® L-61 wire, this flux is capable of achieving impact values exceeding 27 Joules (20 ft·lbf) at extremely low temperatures down to -40°C (-40°F). This makes it suitable for applications requiring ductility and resistance to brittle fracture in cold environments. The product conforms to EN ISO 14174 – S A AB 1 standards, validating its quality and performance consistency for structural and general welding projects.

Quality assurance is paramount with Lincoln Electric consumables. Each lot of Lincolnweld 860 is tested, and Actual (Type 3.1) certificates showing specific chemical composition, particle size distribution, and moisture levels are available. This transparency ensures that welding engineers and quality control managers can rely on the flux for code-compliant work. Packaged in a durable 50 lb bag, the flux is protected from environmental contaminants, though proper storage in a dry environment or rod oven is recommended to maintain low hydrogen levels in the weld deposit.

This flux is categorized under general purpose SAW fluxes but stands out due to its versatility and industry-wide acceptance. It is particularly effective for welding mild steel and low alloy steels (MSLA), providing a smooth bead profile and minimizing post-weld cleanup time. For industrial operations looking for a reliable, high-performance flux that balances ease of use with robust mechanical properties, the ED019589 Lincolnweld 860 is the standard solution.
