SANDVIK
Sandvik 25.10.4.L-T1 (2594L-T1) is a high alloyed chromium-nickel-molybdenum-nitrogen flux core electrode for welding of for welding of 25%Cr super duplex (ferritic-austenitic) stainless steels (e.g. Sandvik SAF 2507 and Zeron* 100).
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 25.10.4.L-T1 (2594L-T1) gives smooth, uniform beads and works in any standard weld position.
