At Nasir Nickel Alloys in Manama, Bahrain, Incoloy 800/800H/800HT Fasteners are developed to deliver exceptional performance in high-temperature and corrosive service conditions. These fasteners, manufactured from iron-nickel-chromium alloys, offer superior strength, oxidation resistance, and metallurgical stability during prolonged exposure to elevated temperatures. The variations—800, 800H, and 800HT—provide enhanced creep and stress-rupture properties, making them ideal for demanding industrial systems. Incoloy 800/800H/800HT Fasteners ensure long-term reliability in environments involving thermal cycling, carburization, and aggressive chemicals, supporting operations where safety, durability, and temperature resistance are essential.
Incoloy 800/800H/800HT Fasteners are composed of nickel, chromium, and iron, with controlled carbon and aluminum-titanium additions for improved strength. Alloy 800 provides excellent corrosion resistance, while 800H and 800HT offer superior high-temperature creep and stress-rupture performance due to optimized carbon levels. These fasteners exhibit strong tensile and yield strength, excellent oxidation resistance, and stable mechanical properties during long-term exposure to elevated temperatures. Their resistance to carburization, chloride stress corrosion cracking, and thermal fatigue ensures dependable performance in harsh industrial settings.
