Properties And Applications

It is a duplex stainless steel electrode used for welding ferritic-austenitic (duplex) stainless steels containing Cr-Ni-Mo. It is used in the welding of acid tanks and piping systems in the chemical, petrochemical, paper, shipbuilding, and seawater treatment industries. It can also be used for joining duplex stainless steels with carbon steels. The delta-ferrite content of the weld metal is approximately between 25% and 35%. The weld metal has high strength and ductility, and offers excellent resistance to pitting corrosion and stress corrosion cracking in chloride-containing solutions. It can be used in service temperatures up to 250°C. Fine droplet transfer ensures smooth weld seams by providing good fusion with base metal surfaces. Welding can be performed using both AC and DC. Arc striking, re-ignition, and slag removal are easy.
