Description:

Cromacore DW 329AP Duplex is a rutile flux cored wire which deposits a low carbon 23% Cr / 9% Ni /

3% Mo / N duplex stainless steel weld metal with a nominal ferrite level of FN 40. The wire is specially

designed for positional welding and is not recommended for flat or horizontal-vertical applications. It is

intended for welding similar duplex stainless steels which offer an excellent combination of high

strength and very good resistance to chloride induced pitting and stress corrosion cracking. The wire

operates with a very stable, spatter-free arc and produces a bright, smooth weld bead surface and

self-releasing slag. Cromacore DW 329AP Duplex is ideal for high productivity welding in the vertical

position.
