TOKO SAW Flux Product Line
From carbon steel to high-strength steel, from stainless steel to pipeline-specific grades, TOKO provides complete SAW flux solutions. All products strictly comply with AWS / ISO standards, ensuring weld quality and productivity.
SJ101 Agglomerated Flux
Designed for high-strength steels, quenched & tempered steels, offshore structures and wind towers. Ultra-low hydrogen (≤4ml/100g), excellent impact toughness at -40°C, achieving >70J CVN with Ni-alloyed wires. Ideal for thick-plate multi-pass welding with superb slag release.
SJ301 Fused Flux
Economical fused flux for carbon steel, marine steel and general structural steel. Low moisture pickup, AC/DC compatible, smooth bead appearance. Excellent porosity resistance, ideal for mass production and automated welding.
SJ501 Agglomerated Flux
Suitable for high-tensile steels, crane booms, mining equipment and military vehicles. Excellent alloy compensation, works with Mo, Cr-Mo wires to significantly enhance weld strength. Good impact toughness, suitable for high heat input welding.
HJ107 Pipeline Flux
Specifically designed for API 5L X60–X80 line pipe and offshore pipelines. Ultra-low hydrogen (≤3ml/100g), excellent CTOD performance and impact toughness at -50°C. Optimized for narrow-groove welding with minimal porosity. When used with AWS A5.28 ER80S-G wire, it delivers high-strength, high-toughness welds.
HJ260 High-Speed Flux
Ideal for automotive frames, railway components and high-volume carbon steel fabrication. Stable arc at high current, excellent slag release, insensitive to rust and mill scale on base metal. Significantly improves welding speed and reduces production costs – a reliable partner for automated lines.
HJ431 Stainless Steel Flux
Developed for 304, 316, 347 austenitic stainless steels. High Cr recovery, low carbon transfer, effectively prevents intergranular corrosion. When used with AWS A5.9 309L/316L wires, it provides excellent corrosion resistance, suitable for chemical, food, and pharmaceutical grade equipment.
