Detailed Product Description

welding flux

1. Commodity: Welding flux

2. Type : AWS A5.17 EM-12K (Sj301)

3. Description :
Versatile flux for welding of low alloy structural steel and boiler steel in combination with appropriate SAW wire(such as EM12K and EL12),which can obtain smooth weld bead with flat weld interfaces free from undercut. Steadily arc and easy slag removal, no phenomenon of slag-flow . It can be applied to the Multi-pass weld and multi-wire weld, especially to weld pipelines in various diameters.

4. Flux type: silicon calcium

5. Grain size: 2.00-0.28mm (10-60mesh)

6. Typical weld metal analysis: (Wt%)

C : 0.08 , Si: 0.52 , Mn : 0.95 , S:0.028 , P: 0.028

7. Typical Flux Composition:

SiO2+TiO2 :25-35% , CaO+MgO: 15-25%, Al2O3+MnO: 30-40%, CaF2:5-15%,
8. Typical weld metal mechanical properties:

Yield stress: ≥400Mpa , Tensible strength :480-660Mpa , Elongation: 24% ,

AKV(J) ≥27 / -20deg

9. Packing: Plastic-lined paper bag of 25KG each. 1000kg/pallet

10. storage:To ensure the integrity of welding flux over an extended period, flux should be stored indoors in a dry place. Moist flux can be redried at300-350°C for 2 hours. Both heating and cooling must be carried out slowly.
