Fajar Metals, a reputable manufacturer and supplier based in Jakarta, Indonesia, specializes in high-performance Inconel 718 Nuts that are perfect for critical fastening applications in extreme conditions. Crafted from Inconel 718, a nickel-based superalloy celebrated for its remarkable strength, heat resistance, and corrosion resistance, these nuts are well-suited for both cryogenic and high-temperature environments. Adhering to standards like ASTM F2281, ASTM B637, and ASME specifications, Fajar Metals offers a diverse range of nut types, including hex nuts, heavy hex nuts, and lock nuts. These components find extensive use in aerospace, nuclear, marine, and petrochemical industries, ensuring secure and durable fastening.
Inconel 718 Nuts are made up of about 50–55% Nickel, 17–21% Chromium, along with Molybdenum, Niobium, Titanium, Aluminum, and Iron. This alloy is precipitation-hardened, providing impressive strength and toughness across a wide temperature spectrum. Typically, these nuts showcase tensile strength reaching up to 1240 MPa, yield strength around 1035 MPa, and outstanding resistance to stress corrosion cracking, oxidation, and creep. Their mechanical stability spans from cryogenic temperatures all the way up to 700°C, making them ideal for extreme environments that demand secure and long-lasting fastening solutions.
