Selectarc FCO 309L

This flux-cored wire, designated FCO 309L, is specifically designed for welding stainless steel 309L and for heterogeneous assembly with stainless steel and low alloy steels. It’s characterized by its low spatter, self-releasing slag, and excellent weldability, even in challenging outdoor conditions. The wire is particularly suitable for flat and half up/half down welding positions. It’s compliant with AWS A5.22 : E309LT0-3 and ISO 17633-A : T 23 12 L U NO 3 standards.

This wire is ideal for applications requiring high weldability and performance with 309L stainless steel and compatible alloys. Common uses include welding as a buffer layer, rebuilding hardfacing applications, and general fabrication work where reliable welds in diverse conditions are critical. It is particularly beneficial in outdoor environments due to its robust performance.
