Description:
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.
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.
