Description:

Cromacore DW 309L is a 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. The wire operates with a very stable,

spatter free arc producing a bright, smooth weld bead surface and self-releasing slag. Cromacore DW

309L is used mainly for downhand and horizontal-vertical welding and is ideal for standing fillets.

Applications:

Dissimilar joints between stainless and mild or low alloy steels.

Buffer layers on mild and low alloy steels prior to overlaying with Cromacore DW 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.
