JACKSUN NOVA 316LF

AWS A5.4: E316L-16 (Nr.)

JACKSUN NOVA 316LF is a rutile-coated, low-carbon, niobium-stabilized stainless steel electrode, conforming to AWS A5.4 E316L-16 (Nr.) and EN ISO 3581-A E 19 12 3 Nb L R 12.

Specially designed for welding AISI 316L stainless steels, where improved resistance to intergranular corrosion is required in the as-welded condition.
The niobium stabilization prevents carbide precipitation at grain boundaries, even under severe operating conditions.
Excellent performance in chloride-rich environments, offering superior pitting resistance compared to standard 316L.
Recommended for chemical processing, fertilizers, marine structures, desalination plants, and food/pharma equipment.
