Exaton 23.12.2.LR is a high alloyed chromium-nickel-molybdenum covered electrode with rutile coating for welding of dissimilar joints between stainless steel and mild or low alloyed steels. It is also used to create buffer layers with a composition of 18%Cr/8%Ni/2%Mo before overlay alloys are deposited. The electrode has excellent arc stability, low spatter and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self peeling slag, easy post weld finishing. Exaton 23.12.2.LR gives smooth uniform beads and works in any standard weld position. Typical applications are welding of stainless steels to mild or low alloy steels, buffer layers on low alloy steels before overlays of 316 composition, welding of medium carbon hardenable steels e g armor plate.
