Discription and applications:
Acid agglomerated flux for welding of low carbon steel in combination with appropriate SAW (such as EL8, EM12, EM12K). SJ503 can produce welding bead with anti blow hole ability and anti-cracking. Especially used to the double-layer with single pass weld and fillet weld.
