Thermanit 25/09 CuT TIG rod
Classifications high-alloyed
EN ISO 14343-A: AWS A5.9:
W 25 9 4 NL ER2594
Characteristics and field of use
Super duplex stainless steel resistant to intercrystalline corrosion (Service temperature: –50 °C up
to +220 °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 supermartensitic stainless steels (13 % Cr) extra low hydrogen in the filler material
available0n request.
