It is 25%Cr-9%Ni-4%Mo-N austenite and ferrite duplex stainless steel flux-cored wire shiled by CO2. Because it has  very low carbon content, and contains a certain amount of molybdenum and nitrogen, deposited metal has excellent resistance to pitting corrosion and stress corrosion cracking performance (PRE≥40). It is suitable for the welding of marine oil, gas and petrochemical industry such as welding 00Cr25Ni7Mo4N.
