MAXFLUX SAF-223 (SPL)

AWS: SFA 5.17/5.23 F7A2-EL8, F7A4/A5-EM12K,F7A4/P4-EH14, F8A2-EA2-A2 EN ISO CODE: 14174 SA FB 1 67 DC

Maxflux SAF-223 (SPL) is an agglomerated basic type flux for high-speed longitudinal welding giving smooth bead and easy slag removal characteristics. The flux is also suitable for Tandem, 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 (SPL) is suitable for Tandem single & multi-layer welding of pressure vessel grade steels (EN 10028-2), pipes conforming to X-42 to X-70 grade of API 5L, Grade 1/2/3 of ASTM A252, SA 516 Grade 70, Grade A/B of A53 & A523 specification, etc. Suitable for AC and DC welding.

Precaution

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