Welding flux

Welding flux for a variety of welding methods and a wide range of applications.
The Sandvik program includes flux for:
- Submerged arc welding (SAW)
- Electroslag welding (ESW)
- Joining of plates with wire electrodes
- Stainless steel, high-alloy steels and nickel alloys
Previous designation Material Safety Data Sheets (MSDS)
When choosing a welding flux for a given combination of strip/wire electrode and parent metal, the welding parameters also have to be considered to obtain the desired composition of the weld metal.

Flux for submerged-arc welding (SAW)
Flux | Characteristics1) | Applications |
---|---|---|
Sandvik 10S | Slightly Cr compensated Basicity 1.0 |
General purpose flux for both strip and wire electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized. Good slag removal. Gives about 2% lower ferrite content than 10SW. |
Sandvik 10SW | Cr compensated Basicity 1.0 |
General purpose flux for both strip and wire electrodes of CrNi and CrNiMo steels, stabilized or non-stabilized. Good slag removal. Gives about 2% higher ferrite content than 10S. |
Sandvik 15W | Non-Cr compensated Basicity 1.7 |
Special purpose flux for wire electrodes of Cr-Ni and CrNiMo steels, stabilized or non-stabilized as well as duplex, super-duplex and fully austenitic grades, e.g. 20.25.5.LCu. Good slag removal. Gives good impact properties. The Nb burn-off is very small when using stabilized electrodes, such as 19.9.Nb. |
Sandvik 31S | Non-Cr compensated Basicity 1.1 |
Single purpose flux for both strip and wire electrodes of 25.22.2.LMn, intended for urea applications. Good slag removal. |
Sandvik 50SW | Non-Cr compensated Basicity 2.4 |
General flux for strip and wire electrodes of nickel alloys. Good slag removal. |
Sandvik 52W2) | Non-Cr compensated Basicity 1.4 |
Flux for wire electrodes of nickel alloys as well as fully austenitic CrNi, e.g. 25.20.C, or CrNiMo grades, e.g. 27.31.4.LCu. Good slag removal. |
