SJ101 Welding Flux
Designed for demanding applications requiring superior low-temperature impact toughness and ultra-low hydrogen content. SJ101 delivers consistent weld quality in multi-pass welding of thick plates, with excellent slag release and porosity resistance.
Why Choose TOKO SJ101?
Engineered for the toughest welding conditions – SJ101 delivers performance that exceeds industry standards.
Exceptional Low-Temperature Toughness
Charpy V-notch impact energy >70J at -40°C, ensuring structural integrity in arctic and offshore environments.
Ultra-Low Hydrogen (≤4ml/100g)
Minimizes risk of hydrogen-induced cracking, critical for high-strength steel and thick-section welding.
Superb Slag Detachability
Self-releasing slag system reduces post-weld cleaning time and improves productivity in multi-pass operations.
High Heat Input Capability
Optimized for high deposition rates and thick-plate welding without compromising mechanical properties.
Offshore & Marine Grade
Approved for shipbuilding and offshore structures, with excellent resistance to seawater corrosion and fatigue.
Versatile Wire Compatibility
Works seamlessly with AWS A5.23 EB3, EB6, and other Ni-alloyed wires for tailored weld metal properties.
