Premiarc DW-309L
Premiarc DW-309L is a rutile flux-cored wire that produces low-carbon 24% Cr / 13% Ni type stainless weld metal.
Premiarc DW-309L is a rutile flux-cored wire that produces low-carbon 24% Cr / 13% Ni type stainless weld metal. The weld metal has a ferriticity of approximately FN 14 (= 1.2 ferrite number). The arc burns very stably and without spatter, with a bright and smooth burn surface and self-slagging. The Premiarc DW-309L is mainly used for foot and bottom welds and is particularly ideal for small welds.
