Product Description
Inconel 625 (UNS N06625) and Inconel 718 (UNS N07718) are premium nickel-chromium superalloys widely specified for nuclear applications. Inconel 625 offers outstanding resistance to a wide range of corrosive media and excellent fabricability, while Inconel 718 provides higher strength through precipitation hardening and maintains performance under elevated temperature and stress.
Both alloys are supplied as high-quality bar stock suitable for machining nuclear-grade fasteners, structural parts and reactor internals. These nickel alloy bars combine corrosion resistance, high strength and dimensional stability, making them preferred choices for pressurized water reactors (PWR), boiling water reactors (BWR) and related nuclear systems.
