Elvis Nickel Alloys, a top-notch supplier and manufacturer located in Houston, USA, specializes in high-performance Inconel 718 Stud Bolts. These bolts are engineered to withstand extreme service conditions, including high temperatures, pressure, and corrosive environments. Crafted from Nickel-Chromium alloy Inconel 718 (UNS N07718), they boast remarkable strength, oxidation resistance, and creep resistance, even at temperatures soaring up to 700°C (1290°F). Precipitation-hardened for enhanced mechanical strength, these bolts find their place in critical applications across industries like aerospace, oil & gas, nuclear, and chemical processing. They comply with international standards such as ASTM B637, ensuring they deliver performance, reliability, and safety in the toughest conditions.
Inconel 718 Stud Bolts are made up of roughly 50–55% nickel, 17–21% chromium, 2.8–3.3% molybdenum, and 4.75–5.5% niobium, along with trace amounts of iron, titanium, and aluminum. This unique blend provides excellent resistance to oxidation, chloride stress corrosion, and high-cycle fatigue. These bolts achieve a tensile strength of over 1380 MPa and a yield strength exceeding 1000 MPa, along with outstanding creep rupture strength. The precipitation hardening process through heat treatment significantly enhances their strength while maintaining ductility, making them perfect for high-stress environments that demand long-lasting reliability and resistance to mechanical and thermal wear.
