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