2.4650 (Nimonic 263) Forgings — Rings, Flanges, Bars & Discs
Open-die forged 2.4650 / Nimonic 263 (UNS N07263) supplied by Jiangyin Jiangnan Metal Co., Ltd., a nickel-alloy forging factory in Jiangsu, China. Custom sizes and drawings, ultrasonically tested, with EN 10204 3.1/3.2 certificates.
2.4650 is the Werkstoff (DIN/EN) material number for Nimonic 263, also known as Alloy 263, Haynes 263, Nicrofer 5120 CoTi or UNS N07263. It is an age-hardenable nickel-cobalt-chromium-molybdenum superalloy designed for excellent fabrication in the annealed condition together with high aged strength. 2.4650 offers high strength, good corrosion and oxidation resistance, and high-temperature ductility in welded structures for service up to about 850 °C.
