What is the material number for Inconel 718?
The primary material number for Inconel 718 is UNS N07718, with other common designations including W.Nr. 2.4668 (Werkstoff) and various AMS (Aerospace Material Specification) numbers like AMS 5662, 5663, or 5596, depending on form and condition (e.g., bar, sheet, forged).
What material is 2.4668 equivalent to?
Material 2.4668 (Werkstoff Nr. 2.4668) is a German standard designation for the high-strength, corrosion-resistant Nickel Alloy 718, also known as Inconel 718, with the UNS designation N07718, widely used in aerospace and oil/gas for high-temperature applications.
What are the standards for Inconel 718?
Inconel 718 standard specifies its composition (nickel-chromium-iron superalloy, containing niobium/titanium) and properties, and is regulated by organizations such as ASTM, SAE (AMS 5662/5663), API, and NACE. These standards define its mechanical strength (minimum tensile strength 1275 MPa, yield strength 1034 MPa), corrosion resistance (resistance to sour gas corrosion), high-temperature creep strength (up to approximately 700°C), and processing methods (solution treatment and age hardening heat treatment), making it suitable for aerospace and oil and gas applications.
