MAXFLUX SAF -223

AWS: SFA 5.17/5.23 F7A4EH-14, F7A4EM-12K, F8A2EA2-A2

Maxflux SAF-223 is an agglomerated basic type flux for high-speed longitudinal welding giving smooth & shiny weld bead along with easy slag removal characteristics. The flux is also suitable for multi-wire submerged arc welding applications and supports to achieve higher throat thickness in welding of fillet joints due to higher current carrying capacity.

Maxflux SAF-223 is suitable for single & multi-layer welding of pressure vessel grade steels (EN 10028-2), X-42 to X-70 grade pipes conforming to API-5L specification, etc. 

Precaution

Re-dry the flux at 300-350°C for two hours before use.
