Description:
Cromatig 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.
