Stainless Steels

FW 347 Si 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 Nb reduces the possibility of intergranular chromium carbide precipitation and thus susceptibility to intergranular corrosion and high temperature strength. Silicon improves the usability of the filler metal. It is suitable for welding Cr -Ni stabilized stainless steels of type AISI 347, 321, etc.
