Description:

Cromamig Duplex deposits a 23% Cr / 9% Ni / 3% Mo / N austenitic/ferritic duplex stainless steel

weld metal with a ferrite content of about FN 35.

It is intended for welding similar composition duplex stainless steels which offer an excellent

combination of much higher strength and very good resistance to pitting and stress corrosion

cracking, compared to standard austenitic stainless steels.

Welding current:

DC+
