Nickel Alloy Fasteners

Inconel is a registered trademark of Special Metals Corporation that refers to a family of austenitic nickel-chromium-based superalloys.[1] Inconel alloys are typically used in high temperature applications. It is often referred to in English as "Inco" (or occasionally "Iconel"). Common trade names for Inconel include: Inconel 625, Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 and Nicrofer 6020.[2]

The Inconel family of alloys was first developed in the 1940s by research teams at the Wiggin Works in Hereford, England, in support of the development of the Whittle jet engine.

Composition

Different Inconels have widely varying compositions, but all are predominantly nickel, with chromium as the second element.

Different Inconel alloys

Inconel 600: Solid solution strengthened

Inconel 625: Acid resistant, good weldability

Inconel 690: Low cobalt content for nuclear applications, and low resistivity[16]

Inconel 718: Gamma double prime strengthened with good weldability

Inconel 751: Increased aluminum content for improved rupture strength in the 1600'F range[17]

Inconel 792: Increased aluminum content for improved high temperature corrosion properties, used especially in gas turbines

Inconel 939: Gamma prime strengthened with good weldability
