Sandvik 15W is a basic, agglomerated flux for use with all austenitic stainless wire electrodes, especially when high impact strength is aimed. It is particularly suited for Sandvik's range of duplex wire electrodes, in particular Sandvik 22.8.3.L and 25.10.4.L due to the excellent impact properties obtainable in the weld metal. The relatively high basicity also makes Sandvik 15W suitable for use in fully austenitic welds where good hot cracking resistance is necessary. Due to its low niobium content burnoff it can be used advantageously with stabilized wire electrodes, such as AWS 347 and 318.
