Avesta FCW 2507/P100-PW description: Avesta FCW 2507/P100-PW is a rutile flux cored wire designed for welding ferritic-austenitic superduplex stainless steel Outokumpu 2507 (S32750/1.4410) and equivalent steel grades such as Zeron 100 (S32760/1.4501). Avesta FCW 2507/P100-PW can also be used for joints between 2507 and austenitic stainless steels or carbon steels. Superduplex steels are particularly popular for deslination, pulp and paper, flue gas cleaning and sea water systems. The properties of the weld metal fully 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. The operating temperature range is –50°C to 220°C.
