JACKSUN NOVA 347

AWS A5.4: E347-16

JACKSUN NOVA 347 is a rutile-coated stainless steel electrode conforming to AWS A5.4 E347-16 and EN ISO 3581-A E 19 9 Nb R 12.
Stabilized with niobium (Nb) to resist intergranular corrosion.
Weld metal composition similar to E308, but with Nb for improved resistance to carbide precipitation.
Excellent for welding AISI 321 and 347 stainless steels, especially for service in high-temperature or corrosive environments.
Provides smooth arc, easy slag removal, and excellent bead appearance.(As per AWS A5.4 E347-16 / EN ISO 3581-A E 19 9 Nb R 12)
