FW 409Nb
AWS: SFA 5.9 ER409Nb
EN ISO CODE:
FW 409Nb is a solid wire for TIG welding, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. This wire is depositing 12Cr – 0.5Ni - 1Nb weld metal. Added Nb in weld metal to produce a ferritic microstructure with fine grains. It is ideally suited for welding ferritic stainless steels such as 405 and 409. It is also suitable for overlay on carbon steels, low alloy steels, 410 stainless steel, etc.
