Standard：AWS A5.9, ER2594.
It is 25%Cr-9%Ni-4%Mo-N austenite and ferrite super duplex stainless steel solid wire shielded by 98%Ar+2%O2.
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.
