At Nasir Nickel Alloys in Manama, Bahrain, Inconel 718 Fasteners are engineered to deliver exceptional high-temperature strength, corrosion resistance, and long-term durability. Manufactured from a nickel-chromium alloy strengthened by niobium and molybdenum, these fasteners maintain excellent mechanical stability even at temperatures up to 1300°F (700°C). Inconel 718 is known for its outstanding resistance to oxidation, pitting, and stress corrosion cracking, making it ideal for harsh industrial environments. These fasteners ensure reliable performance in aerospace, power generation, chemical processing, marine engineering, and high-pressure systems, where superior mechanical strength and corrosion resistance are essential for safety and longevity.
Inconel 718 Fasteners are composed mainly of nickel and chromium, with added niobium, molybdenum, titanium, and aluminum to enhance strength through precipitation hardening. The alloy offers exceptional tensile strength, fatigue resistance, and high creep-rupture properties across a wide temperature range. It maintains excellent fabricability and weldability compared to other superalloys. Inconel 718 also exhibits strong resistance to oxidation, chloride-induced corrosion, and corrosive chemicals, ensuring reliability in extreme environments. These mechanical and chemical properties make the fasteners suitable for high-stress, high-temperature, and corrosive applications.
