| Sandvik 24.13.L–T0 (309/309L) 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 before overlay alloys are deposited. 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 24.13.L–T0 (309/309L) gives smooth, uniform beads and works in the flat and horizontal fillet weld positions. Applications: Sandvik E317TO-1/T0-4 (309/309L) is used for welding steels of the following types: - Welding of stainless steels to mild or low alloy steels
- Buffer layers on low alloy steels before overlays of 304 composition
- Welding of stainless steels of 23%Cr/12%Ni (309) type
- Welding of medium carbon hardenable steels, e.g. armour plate
- When a weld metal similar to the parent metal is not required, Sandvik 24.13.L-T0 (309/309L) can be used for welding ferritic and martensitic steels
