EN ISO CODE:

Maxflux SAF-223 (Mod) is an agglomerated basic type flux for high speed welding of longitudinal pipe giving smooth & shiny weld bead with improved impact toughness properties. 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 (Mod) 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.
