AWS: AWS/ASME SFA-5.17 F6A0-EL8 F7A2-EM12K F7A4-EH14
SAW wires: EL8, EM12K, EH14, etc.
Power supply: DC (DCEP), AC
Basicity: 1.8 BIIW
Grain size: 10-60 mesh (0.28-2.0mm)
Alloy transfer: nearly no transfer of Mn, Si to weld metal
Category: submerged arc welding mild steel & low-alloy steel
Industry: structural steel, pressure vessel, bridge building, ship building, pipeline, heavy equipment, spiral pipe mills, etc.
Description:
fluoride based agglomerated flux. Granular size 10-60 mesh (0.28-2.0mm). Easy slag removal.
Excellent mechanical properties. Smooth welding pass. Widely used for
API grade X60, X65, X70 pipeline construction. Low diffusible hydrogen
content (≤50ml/100g) in weld metal gives it high toughness and high cracking resistance at low temperature.
Package: damp-proof packing, 25kg/bag
Certification: ABS, CCS, LR

Attention:
1. We get
values in data sheets from tests carried out in accordance to AWS and GB
standard procedure. They only represent values we get under those
conditions. They are not to be taken as guarantees. As to welding,
individual test results may vary depending on experience &
technique, flux type, base metal, joint preparation,
flux preparation, ampere, voltage, etc.
2. If welding fluxes are stored in improper environment or influenced by
condensed moisture, anyway, they get damp, please dry them at 300-350℃ for 2 hours before usage.
3. Please clean the rust, oil, water on base metal before welding.
4. Add minumum 20% new flux when using
recovered flux to avoid welding defects and maintain welding performance
& mechanical properties.
5. Please control parameters properly, like preheat temperature, interpass temperature, cooling rate.
