Cromacore DW 309MoLP is a fully positional 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. Ideal for high productivity
welding in the vertical position.
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.
