Inconel 718 is a molybdenum, niobium, and titanium-bearing nickel-chromium alloy that possesses excellent mechanical properties such as high tensile strength of up to 1240 MPa and high creep resistance up to 704°C. The alloy has good corrosion resistance in different oxidizing as well as reducing environments. Its precipitation hardening capability makes the alloy strong while still having good formability and weldability, making it suitable for high-stress, complex piping components.
