Description: HBF-No.5 submerged arc welding flux,Agglomerated acid flux for welding of ordinary carbon manganese, low alloy structures and boiler quality steel in combination with appropriate SAW wire (such as EL12, EM12K). The flux suitable for high speed welding and provides very good weld bead appearance and excellent slag removal even with small angle preparation and fillet welds. The chemical nature provides high resistance to cracking. Additional features are resistance to porosity when welding rusty plate and low sensitivity towards arc below

Application: Especially being applied to double-side with single pass weld and fillet welds.

Package:25kg in one paper bag.
