Rutile flux-cored wire of T 23 7 N L P / E2307T1 type for welding the lean duplex stainless steels LDX 2101® 1.4162 / UNS S32101), 2304 (1.4362 / UNS S32304) and similar alloys. The combination of excellent strength and better resistance to pitting corrosion, crevice corrosion and stress corrosion cracking than 1.4301 / 304 and 1.4307 / 304L makes this alloy suitable for construction for instance storage tanks, containers, heat exchangers and pressure vessels. Thanks to the low molybdenum content, the resistance to pitting corrosion and stress corrosion cracking in nitric acid containing environments is very good. Typical applications are within civil engineering, transportation, desalination, water treatment, pulp & paper, etc. FOXcore 2307-T1 has a stronger arc and a faster freezing slag compared to FOXcore 2307-T0. It is designed for all-round welding and can be used in all positions without changing the parameter settings. Weldability is excellent in the vertical-up and overhead welding positions. The wire is over-alloyed with nickel to promote weld metal austenite formation. Ferrite measured with FeritScope MP30: ≥ 30 FN. Suitable for service temperatures from –50°C to 250°C.
