TOKO SAW Flux Grades

TOKO SJ101 (Agglomerated Flux)

Agglomerated

Application: Designed for welding high-strength, low-alloy (HSLA) steels and quenched & tempered steels. Ideal for structural components requiring high impact toughness (e.g., offshore platforms, bridges, pressure vessels).

Low hydrogen content to prevent cracking in high-strength steels.
Produces welds with excellent Charpy impact toughness at low temperatures (down to -40°C/-40°F).
Compatible with Ni-based welding wires (e.g., AWS A5.23: EB3, EB6) for enhanced strength and ductility.
Smooth slag detachment and minimal spatter.

Standards: Meets AWS A5.23 specifications.

TOKO SJ301 (Fused Flux)

Fused

Application: Primarily used for welding carbon steels and mild steels in general fabrication. Common in shipbuilding, pipelines, and heavy machinery.

High stability with AC or DC welding currents.
Produces clean, uniform welds with good bead appearance and minimal porosity.
Low moisture absorption due to fused manufacturing process.
Compatible with AWS ER70S-3/ER70S-6 wires.

Standards: Conforms to AWS A5.17 (F7A2-EM12K).

TOKO SJ501 (Agglomerated Flux)

Agglomerated

Application: Tailored for low-alloy steels and high-tensile steels (e.g., ASTM A514, A517). Used in mining equipment, crane booms, and military vehicles.

Alloy compensation to maintain weld metal strength and toughness.
Works with Mo- or Cr-Mo-based wires (e.g., AWS A5.23: EH14).
Excellent crack resistance and adaptability to high-heat-input welding.
Suitable for multi-pass welding.

TOKO SJ302 (Fused Flux)

Fused

Application: General-purpose flux for carbon steels and mild steels. Widely used in automotive, rail, and construction industries.

High deposition rates with minimal slag inclusion.
Good arc stability and bead profile.
Compatible with AWS ER70S-6 wires.

TOKO SJ102 (Agglomerated Flux)

Agglomerated

Application: For welding micro-alloyed steels and API-grade pipeline steels (e.g., X60-X80). Common in oil/gas pipeline construction.

Low hydrogen and excellent low-temperature toughness.
Optimized for high-speed welding with narrow groove joints.
Compatible with high-purity wires (e.g., AWS A5.28: ER80S-G).

TOKO SJ601 (Agglomerated Flux)

Agglomerated

Application: Designed for stainless steel welding (e.g., 304, 316 grades). Used in chemical tanks, food processing equipment, and heat exchangers.

Chromium recovery to maintain corrosion resistance.
Low carbon content to prevent sensitization.
Compatible with 309L/316L wires for matching chemistry.

General Characteristics of TOKO SAW Fluxes

  • Flux Types:
    • Agglomerated: Better for alloyed steels, allows precise control of weld metal chemistry.
    • Fused: Economical, stable, and low-moisture for carbon steels.
  • Performance:
    • Moisture Resistance: Fused fluxes (e.g., SJ301) resist moisture better; agglomerated fluxes (e.g., SJ101) require baking before use.
    • Slag Detachability: Agglomerated fluxes often produce easier-to-remove slag.
  • Compatibility: Always pair with the recommended welding wire (e.g., SJ101 + Ni-based wire for HSLA steels).
  • Industries Served: Energy, shipbuilding, construction, heavy machinery, and pipelines.

Why Choose TOKO SAW Fluxes?

  • Proven Reliability: Trusted in critical applications across multiple industries.
  • Consistent Quality: Uniform performance and predictable results.
  • Technical Support: Expert guidance on flux selection and application.
  • Global Compliance: Meets international standards for welding applications.
