Agglomerated submerged arc welding flux SJ601

welding flux for stainless steel


Name:                  Agglomerated submerged arc welding flux SJ601

SAW wires:          AWS A5.9 ER308, ER308L, ER316, etc.

Power supply:       DC (DCEP), AC

Basicity:                1.8 BIIW.

Grain size:           10-60 mesh (0.28-2.0mm)

Alloy transfer:       Cr

Category:             submerged arc welding of stainless steel & heat-resistant steel & high-alloy steel

Industry:              offshore constructions, offshore drilling platform, oil & gas pipelines, LPG cylinder, etc.

Description:         agglomerated flux. Stable arc, Uniform weld metal surface. SJ601 contains some chromium element, which is a compensation to chromium depletion. It could improve resistance to intergranular corrosion. Welding flux SJ601 is specially suitable for low and ultra-low carbon stainless steel, because it rarely increases the carbon content of weld metal. 

Package:              damp-proof packing, 25kg/bag

Certification:          ISO

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.
