FW 320

AWS: SFA 5.9 ER320

FW 320 is a solid wire for TIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It gives radiographic quality weld deposit. The weld metal provides resistance to intergranular corrosion. Ideally suited to weld base metal of similar composition for applications where resistance to severe corrosion involving a wide range of chemicals, including sulfuric and sulfurous acids and their salts, is required. It can be used to weld both castings and wrought alloys of similar composition.
