Inconel 718 is a nickel-chromium alloy that includes notable amounts of iron, niobium, molybdenum, titanium, and aluminum. Typically, it consists of 50–55% nickel, 17–21% chromium, 4.75–5.5% niobium, and 2.8–3.3% molybdenum. This alloy showcases impressive mechanical strength, boasting a tensile strength of up to 1380 MPa and a yield strength around 1035 MPa. It retains good ductility and toughness even at cryogenic temperatures and elevated heat levels up to 700°C. Its remarkable fatigue, creep, and rupture strength make it perfect for high-pressure, high-temperature valve applications.
