EN ISO CODE:
Mergearc SAF- 723 is an agglomerated flux to weld both medium & high tensile strength structural steels. The flux works at reasonably higher welding speed giving smooth bead and easy slag removal characteristics. The flux is also suitable for multi-wire SAW applications with good CVN toughness. The weld metal gives very less diffusible hydrogen (<5 ml/100gms of weld metal) and radiographic quality deposits. '
Mergearc SAF-723 flux is suitable for single & multilayer welding of various structural, pressure vessels & other medium to high tensile strength steels. Especially suitable for welding of ASTM class steels: A204 Grade A, A516 Gr. B, C & IS 2002type B, API Gr. 5L X60-X 80 etc.
