MAXFLUX SAF-4 (SPL )
AWS: SFA A 5.17 F7A4-EM12K, F7A4/ P4-EH14, F7A4/ P4-EH10K
EN ISO CODE: 14174 SA FB 1 67 DC
Maxflux SAF-4 (Spl) is a basic type flux giving good sub-zero impact properties and resistance to cracking. Slag detachability is very good with smooth & shiny bead finish. The diffusible hydrogen content of weld metal is low & satisfies radiographic quality requirements.
Maxflux SAF-4 (Spl) is suitable for single & multi-layer welding of structural steels, pressure vessels, boilers and other fabrications involving medium tensile & low alloy steel.
