Description:
Cromacore DW 329A 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
designed for welding in the flat and horizontal-vertical positions only and is ideal for standing fillets. 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.
Cromacore 329A Duplex operates with a very stable, spatter-free arc and produces a bright, smooth
weld bead surface and self-releasing slag.
