JACKSUN NOVA 308L

AWS A5.4 E308L-16

JACKSUN NOVA 308L is a low-carbon stainless steel solid wire for MIG (GMAW) and TIG (GTAW) welding.
Designed for welding 304L and 308L stainless steels.
Low carbon (L-grade) reduces the risk of intergranular corrosion.
Produces welds with excellent mechanical properties and resistance to oxidation up to 870 °C.
Stable arc, smooth bead appearance, and minimal spatter.
Suitable for welding stainless steel in chemical, food processing, brewery, and petrochemical applications.
