FLUX CORED WIRE ELECTRODES

DATASHEET

Sandvik 23.12.2.L-T1 (309LM〇-T1) is a high alloyed chromium-nickel-molybdenum flux core electrode 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 bum off rate. It is also characterized by improved moisture resistance, self-peeling slag and easy post weld finishing. Sandvik 23.12.2.L-T1 (309LM〇-T1) gives smooth, uniform beads and works in any standard weld position.
