| Sandvik 23.12.2.LR is a covered electrode with rutile basic coating for joining of dissimilar materials and it is commonly used also for first layer deposit in ASTM 316 overlays. Spray transfer gives a bead with a finely rippled surface. There is little spatter and very good slag removal. The high alloy composition and ferrite level enable the weld metal to tolerate dilution from dissimilar and difficult to weld materials without hot cracking or brittle microstructures. Applications: Sandvik 23.12.2.LR is used for welding in all positions of stainless steels to carbon or low alloy steels. It is used for dissimilar joints between stainless and low alloy steels, buffer layers on low alloy steels, interface runs in ASTM 316L clad steels and also for joining of medium carbon hardenable steels, e.g. armour plate.
