FIller Metal Breakdown

SW-307NS Cored

SW-307NS Cored is a metal cored wire with a hot cracking resistant austenite weld metal. The tough weld metal has an excellent crack resistance, even when welding steels with very poor weldability. This wire is designed for welding dissimilar steels, 13Mn steels with Reduced weldability and for cladding carbon steels, can also be used As a buffer layer prior to hard surfacing. Designed for high deposition welding of multi-layer standing fillet welds.
