SANDVIK22.9.3.LT1

FLUX CORED WIRE ELECTRODES

DATASHEET

Sandvik 22.9.3.L-T1 (2209L-T1) is a chromium-nickel-molybdenum-nitrogen flux core electrode for welding of for welding of 22-23%Cr duplex (ferritic-austenitic) stainless steels (e.g. Sandvik SAF 2205).

The electrode has excellent arc stability, low spatter and fast burn off rate. It is also characterized by improved moisture resistance, self-peeling slag and easy post weld finishing. Sandvik 22.9.3.L-T1 (2209L-T1) gives smooth uniform beads and works in any standard weld position.
