Inconel 718 Fasteners are manufactured from a nickel-based superalloy composed mainly of nickel, chromium, and iron, with significant additions of niobium, molybdenum, and smaller amounts of titanium and aluminum. This composition provides outstanding strength through precipitation hardening. Mechanically, Inconel 718 offers very high tensile and yield strength, excellent fatigue and creep resistance, and strong oxidation resistance. It maintains toughness and structural stability over a wide temperature range, particularly in high-temperature and high-pressure environments.
