Description:

Cromacore DW 309MoL is a rutile flux cored wire which deposits a 23% Cr/13% Ni/ 2,5% Mo

stainless steel weld metal with a ferrite content of approximately FN 22. The high alloy content and

high ferrite level enable the weld metal to tolerate dilution from dissimilar and difficult-to-weld steels

without cracking. The wire operates with a very stable, spatter free arc to produce a bright, smooth

weld bead surface and self-releasing slag. Cromacore DW 309MoL is used mainly for downhand and

horizontal-vertical welding and is ideal for standing fillets.

Applications:

Dissimilar joints between stainless and mild, low alloy or medium carbon steels.

Buffer layers on mild and low alloy steels prior to overlaying with Cromacore DW 316L/LP.

Interface runs on 316L clad steels.

Joining of medium carbon hardenable steels eg. armour plate.
