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.
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.
