MAXFLUX SAF -723
AWS: SFA 5.23 F8P2-EA4-A4, F8A4/F7P4-EA3-A3
EN ISO CODE:
Maxflux SAF- 723 is an agglomerated flux to weld structural steels. The weld metal possesses good CVN toughness & produces smooth beads and excellent slag detachability. The weld metal gives very less diffusible hydrogen (<5 ml/100gms. of W.M.).
Maxflux SAF-723 is suitable for single & multilayer welding of various structural,
pressure vessels & other fabrication steels. Especially suitable for welding of
ASTM steels: A204 Grade A, A516 Gr. B, C & IS 2002 type B, API Gr. 5L X60-X 80
etc.
