15kg - 1.2mm 2594 Solid Super Duplex Stainless MIG Welding Wire - 2507

15kg - 1.2mm 2594 Solid Super Duplex Stainless MIG Welding Wire - 2507

Gas Shielded

Classification: ER2594

Is intended for welding super duplex alloys such as SAF 2507, ASTM S32760, S32550 and S31260. It can also be used for welding duplex type 2205 if extra high corrosion resistance is required, e.g. in root runs in tubes. Provides a ferritic-austenitic weldment that combines many of the good properties of both ferritic and austenitic steel. Welding without filler metal (i.e. TIG-dressing) is not allowed since the ferrite content will increase drastically and both mechanical and corrosion properties will be negatively affected. Structure: Austenite with 45 – 55 % ferrite. Scaling temperature: Approx. 850 °C (air). Corrosion resistance: Excellent resistance to pitting and stress corrosion cracking in chloride-containing environments. Pitting resistance is in accordance with ASTM G48-A, better than 40 °C.
