MAXFLUX SAF -4 (PW )

AWS: SFA 5.17 F7A4/P4-EM12K, F8A4/F7P5-EH14

EN ISO CODE:

Maxflux SAF-4 (PW) is an agglomerated basic type flux having very good performance with good sub-zero impact properties & extreme resistance to cracking. The flux is especially designed to meet the tensile & Impact requirements after post weld heat treatment condition at 620 C. slag is easily removable & bead finish is smooth & shiny. The diffusible hydrogen content of the weld metal is low.

Maxflux SAF-4 (PW) is suitable for single & multi-layer welding of structural steels, pressure vessels, boilers and other fabrications involving medium tensile & low alloy steel.
