Description:

Cromacore DW 309LP is a fully positional rutile flux cored wire which deposits a low carbon 24% Cr /

13% Ni stainless steel weld metal with a ferrite content of about FN 14. Cromacore DW 309LP

operates with a very stable, spatter free arc producing a bright, smooth weld bead surface and

self-releasing slag. Ideal for high productivity welding in the vertical position.

Applications:

Dissimilar joints between stainless and mild or low alloy steels.

Buffer layers on mild and low alloy steels prior to overlaying with Cromacore 308L/LP or DW 347.

Interface runs on clad steel joints.

Welding of similar composition, 309 type, stainless steels.

Joining of ferritic-martensitic stainless steels.
