    Sandvik 25.10.4.LR (Covered electrodes)

    Datasheet updated 2014-08-19 16:17:14 (supersedes all previous editions)

    Sandvik 25.10.4.LR 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.
