Fajar Metals, a leading manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Inconel 718 Stud Bolts that are designed to perform exceptionally well in the toughest conditions. Crafted from Inconel 718, a robust nickel-chromium superalloy, these stud bolts excel in high-temperature, high-pressure, and corrosive environments. They are produced in accordance with ASTM B637, ASTM F2281, and other global standards, making them a popular choice in industries like aerospace, power generation, petrochemical, and marine. Fajar Metals offers a diverse selection of thread types and sizes, ensuring dependable and secure fastening solutions for both structural and critical equipment applications.
Inconel 718 Stud Bolts are mainly made up of Nickel (50–55%), Chromium (17–21%), along with Molybdenum, Niobium, Titanium, Iron, and trace elements. This alloy boasts remarkable resistance to creep, oxidation, stress-corrosion cracking, and thermal fatigue. Typically, these stud bolts deliver a tensile strength of up to 1240 MPa, a yield strength of 1035 MPa, and impressive elongation with outstanding fatigue resistance. The precipitation-hardening feature of Inconel 718 guarantees that strength is maintained in both cryogenic and high-temperature settings, making these fasteners perfect for extreme mechanical and thermal applications.
