318 (Nb stabilised 316) Stainless steel sub-arc wire.
Applications
Use to weld titanium or niobium-stabilised grades of molybdenum-bearing austenite stainless steels, or as an alternative electrode for unstabilised grades such as 316/316L. It is not recommended for structural service above about 400ºC. It is also used for depositing corrosion resistance overlays and valve seat inlays on medium carbon alloy steels, and for this reason, the electrode is normally supplied with a typical ferrite content of 3-14FN.
