Inconel 718 Superalloy is a nickel-chromium based austenitic material which offers excellent corrosion and oxidation resistance. The alloy is commonly applied as solution treated however is also age hardenable by proper precipitation heat treatment and developed to operate in service temperatures up to 760° C (1400°F).
Alloy 718 is the workhorse of the oil- & gas sector and commonly applied in high-temperature applications. It has decent machinability and weldability, making it a widely selected alloy for various applications especially if high-strength corrosion resistance is required. It’s resistance to post-weld cracking due to the various elements makes it an excellent choice most applications. 718 is available in various sizes and grades, although the most commonly available are per ASTM B-637 and API 6A in Solution Treated and Precipitation Age Hardened conditions.
