WELDING FLUX
DATASHEET
Sandvik 15W is a basic welding flux for submerged arc welding giving good slag removal and a fine bead
appearance. Its relatively high basicity makes it suitable for joining of the austenitic and duplex stainless steel
when high impact strength is desired. Due to its low niobium content burn-off it can be used advantageously
with stabilized wire electrodes.

SANDVIK 15W
Folha de dados atualizada 08/09/2016 13:54:22 (substitui todas as edições anteriores)
Sandvik 15W is a high performance welding flux in many joining applications in the chemical, petrochemical and
oil&gas industry. It is particularly suited for Sandvik's range of duplex wire electrodes (e.g. Sandvik
22.8.3.L/25.10.4.L) due to the highly neutral behaviour, which ensures an optimal balanced microstructure.
Sandvik 15W gives the following mechanical properties for the filler wires below.
