Rutile flux-cored wire of T 23 7 N L R / E2307T0 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 of 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 provides excellent weldability in flat as well as horizontal-vertical position. Welding in vertical-up and overhead positions is preferably done with FOXcore 2307-T1. 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.
