Rutile flux-cored wire of T 25 9 4 N L P / E2594T1 type designed for welding ferritic-austenitic superduplex steel and equivalent steel grades such as 1.4410 / UNS S32570 and 1.4501 / UNS S32760. Can also be used for joints between superduplex grades and austenitic stainless steels or carbon steels. Superduplex steels are particularly popular for desalination, pulp & paper, flue gas desulphurization and sea water systems. Developed to fulfill severe requirements, such as those in NORSOK M-601 and similar standards. Properties of the weld metal match those of the parent metal, offering high tensile strength and toughness as well as an excellent resistance to stress corrosion cracking and localized corrosion in chloride containing environments. Meet the corrosion test requirements per ASTM G 48 Methods A, B and E (40°C). Over-alloyed in nickel to promote austenite formation. Designed for all-round welding and can be used in all positions without changing the parameter settings. The weldability is excellent in the vertical-up and overhead welding positions. The operating temperature range is –50°C to 220°C.
