TIG rod and wire of W 25 9 4 N L / ER2594 type designed for welding of ferritic-austenitic superduplex stainless steels. Resistant to intercrystalline corrosion. Service temperature: from –50º C up to 220º C. Very good resistance to pitting corrosion and stress corrosion cracking due to the high CrMo(N)-content (pitting index ≥40). Well-suited for conditions in offshore application, particularly for welding of 13% Cr super-martensitic stainless steel. (extra low hydrogen version of filler material available on request).
