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.
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.
