FW 320LR
AWS: SFA 5.9 ER320LR
EN ISO CODE:
FW 320LR 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 elements C, Si, P and S maintained as low as possible and Nb & Mn are controlled to get better properties. The weld metal has excellent resistance to oxidation and scaling at 1200°C continuous service. It is primarily used to weld base metals of similar composition for applications where resistance to severe corrosion is required for a wide range of chemicals including sulfuric and sulfurous acid and their salts. The typical applications include HV-9A stainless steel, for fabricating carpenter 20 stainless steels etc.
