Welding wires designed for single- or multilayer surfacing
Sandvik offers three welding wire grades for GTAW, plasma arc welding, GMAW, and SAW.
Characterized by its very low cobalt, vanadium, and boron content and enhanced ferrite content, Sandvik 24.13.LHF has high resistance to hot cracking. The wire is recommended for first-layer weld cladding procedures and dissimilar joining of stainless to low-alloyed or nonalloyed steels, wrought iron, and cast iron. It is also suitable for overlay welding of carbon and low-alloyed steels, where a 304/304L deposit is required.
Sandvik 24.13.LNb offers stability at high temperatures. An overalloyed filler metal, it is recommended for overlay welding of carbon and low-alloy steels that require a type 347 overlay. Its weld deposit is niobium stabilized and thus resistant to carbide precipitation and resultant intergranular corrosion.
Sandvik 24.16.3.L is suitable for welding on oil and gas pipelines and valves. The corrosion resistance of the weld overlays is at the same level as the 316L base metal. The wire is suitable for the buffer layer on steel in multilayer techniques.
