Sanicro 60 (Covered electrodes)
Datasheet updated 2012-08-03 09:09:02 (supersedes all previous editions)
Sanicro 60 is a covered electrode with basic coating with normal metal recovery for welding of nickel alloys and high-alloy stainless steels, such as Sandvik 254 SMO*, Sanicro 63, Alloy 625 and Alloy 825. It can also be used for dissimilar joining of stainless steels to nickel alloys and for overlay welding. There is little spatter and very good slag removal.
