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.
