Rutile flux-cored wire of T 22 9 3 N L R / E 2209T0 type primarily designed for welding 2205 (1.4462 / UNS S32205, S31805) duplex stainless steels used in offshore, shipyards, chemical tankers, chemical / petro-chemical, pulp & paper, etc. Provides excellent weldability in flat as well as horizontal-vertical position. The wide arc ensures even penetration and sidewall fusion to prevent lack of fusion. The wire shows good wetting behavior and results in a smooth weld finish. The weld metal has very good resistance to pitting and stress corrosion cracking in chloride containing environments. Meets the corrosion test requirements per ASTM G 48 Methods A, B and E for 24
h up to 22º C in as-welded condition and 30º C in solution-annealed condition, ASTM G 36, ASTM A262 Practice B, C and E, and NACE TM 0177 Method A. Over-alloyed in nickel to promote austenite formation. Ferrite measured with FeritScope MP30 40 – 50 FN. Suitable for service temperatures from –40º C to 250º C. For welding in vertical-up and overhead positions, FOXcore 2209-T1 is recommended as well as for thicker base material application.
