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.
