MAXFLUX SAF-231
AWS: SFA 5.23 F8P2-EB2/ EB2R-H8
EN ISO CODE:
Maxflux SAF-231 is an agglomerated special flux used for fillet & butt-welding of carbon steel and Cr-Mo steel plates. The active nature of the flux provides an outstanding tolerance to rust, mill scale, etc so that joint preparation during welding is minimized. The superior fusion properties of the flux provide uniform fusion in fillet welds with excellent slag detachability. The flux can also be used for multi-pass welding but shall be restricted to 25mm thickness as it is active in nature. The deposited weld metal is of radiographic quality and the diffusible hydrogen content is<5 ml/100gm of weld metal.
Maxflux SAF- 231 is suitable for single & multilayer welding of various structural,
Boiler, Pressure vessel steels, Petrochemical industries, Refineries, Shipping &
other fabrication industries.
