DIN BAR 188AC10KM
Discription and applications:
Acid agglomerated flux for welding of ordinary carbon, low alloy structure and boiler quality steel matching with suitable SAW wire(such as EL8, EM12, EM12K). The flux suitable for high speed welding and provides very good weld bead appearance and excellent slag detachability even with narrow groove and fillet welds. The other character of HFX-SJ501 is high anti-cracking and anti-blowhole ability. Especially it is insensitive to oil, rust, scale and dirt on the surface to be welded. Most being used to double-side with single pass weld and fillet welds. As the consumption of the flux is very low, It it very economical.

NOTICE:
1. Before welding, fluxes should be baked for 2 hours at 300-350°C.
2. Removal of rust, oil, water and impurities etc. in welding area.
