JACKSUN NOVA 430

AWS/ASME: A5.9 ER430

JACKSUN NOVA 430 is a ferritic stainless steel solid wire designed for MIG (GMAW) and TIG (GTAW) welding applications. It is mainly used for welding type 430 and similar ferritic stainless steels.
Provides good resistance to oxidation, corrosion, and scaling up to ~ 800 °C.
Suitable for automotive, petrochemical, and structural applications where ferritic stainless steels are employed.
Weld deposits exhibit ferritic microstructure and moderate toughness.
