Product Description and Application
W.Nr.2.4668 is also known as UNS NO7718,UNS N07718, NiCr19Fe19Nb5,GH4169 (China), Inconel 718
W.Nr.2.4668 is a Ni-Cr-Fe base precipitation-hardening deformed superalloy with a long-term operating temperature range of -253℃~650℃ and a short-term operating temperature of 800℃. The alloy has high strength below 650℃ and has good fatigue resistance, radiation resistance, oxidation resistance and corrosion resistance, as well as good processability, weldability and long-term structural stability. Suitable for the manufacture of turbine discs, rings, blades, shafts, fasteners and elastic components, plate structural parts, casing and so on in aviation, aerospace, nuclear energy and petrochemical industries. Alloy composition is divided into ordinary and high quality, high-quality W.Nr.2.4668 alloy carbon, niobium, sulfur and gas content control is more strict, mainly used for manufacturing all kinds of rotating parts.
