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.
