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:
Spray transfer gives a bead with a finely rippled surface. There is little spatter and very good slag removal.
