Sandvik 25.10.4.LR (2594-16) is a covered electrode with rutile-basic coating and about 105% metal recovery used for welding of super-duplex (austenitic-ferritic) stainless steels of UNS S32750/S32760 type (e.g. Sandvik SAF 2507 and Zeron* 100).

The weld metal has especially good properties under severely corrosive conditions. Examples of properties are:

  • Excellent stress corrosion cracking resistance in chloride-containing media
  • Excellent pitting resistance
  • High resistance to general corrosion
  • High resistance to erosion corrosion and corrosion fatigue

Spray transfer gives a bead with a finely rippled surface. There is little spatter and very good slag removal. The electrode has excellent arc stability and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self-peeling slag, high resistance to porosity and easy post weld finishing.
