Selectarc Flux UP BF10

This Fluoride-Basic agglomerated flux, designated ISO 14174 S A FB 1 55 AC H5, is specifically formulated for submerged arc welding (SAW). It boasts a high basicity and low impurity levels of phosphorus (P) and sulfur (S), leading to weld deposits with improved mechanical properties, particularly enhanced toughness at low temperatures. The flux’s neutral slag reactions provide precise control over the weld metal’s chemical composition. It’s suitable for use with a variety of DC and AC welding currents, employing single or tandem wire configurations. This flux is compatible with numerous electrode wires, including ISO 14341-A AWS A5.17 series, facilitating versatile applications in construction steels up to 460MPa yield strength, low-temperature steels down to -60°C, and specialized steel grades like S690QL and boiler/vessel steels (16Mo3/A204 gr A, 13CrMo4-5/A387 gr 12, 10CrMo9-10/A387 gr 22).

The FLUX UP BF10 flux is primarily utilized in submerged arc welding (SAW) processes across a range of applications. Its key benefits make it suitable for welding construction steels (up to 460MPa), low-temperature steels (-60°C), and specialized steel grades for boiler and vessel construction. It’s compatible with both DC and AC welding currents and can be used with single or tandem wire configurations, offering flexibility in welding operations. The flux’s ability to control weld metal chemical composition allows for optimized mechanical properties, particularly toughness, in the final weld. Storage recommendations include dry conditions and a maximum one-year shelf life, with optional drying at 300-350°C if needed. Recycling the flux is possible after welding by drying at these temperatures.
