Detailed introduction of Inconel 718 alloy fasteners
Inconel 718 Fasteners are high-strength, nickel-based, superalloy fasteners commonly used in demanding applications due to their excellent mechanical properties and corrosion resistance at high temperatures (up to 1300°F). These fasteners exhibit precipitation hardening properties, achieving high yield, tensile, and creep-rupture strengths through specific heat treatments. Key applications include the aerospace, oil and gas, and power generation industries, where their ability to maintain strength under pressure and extreme temperatures is crucial for safety and performance.
What is the strength of Inconel 718 bolts?
185-220 ksi
Twice as strong as its sister alloy, Inconel 625, Inconel 718 is known for its exceptionally high strength after age hardening (185-220 ksi tensile strength). Inconel 718 bolts maintain their strength even when subjected to pressure and temperatures up to 1300°F (700°C).
