Super duplex stainless steel; resistant to inter-crystalline corrosion. 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 super-martensitic stainless steels (13 % Cr); extra low hydrogen in the filler material available on request. Service temperature: –50 °C to 220 °C (-58°F to 428 °F).
