What are Inconel 800 Fasteners?
Inconel 800 fasteners are top grade fasteners made from nickel-iron-chromium alloy (UNS N08800 / WNR 1.4876). These fasteners have a good resistance towards oxidizing and carburizing atmosphere as well as towards oxidation and sulfidation in addition to good hot corrosion resistance and have a high strength up to 1100°F (593°C). Fastener products commonly seen are Inconel 800 bolts, nuts, screws, threaded bars, stud fasteners etc. in the field of petrochemicals, heat treatment, chemical processing and power generation.

What is Inconel Alloy 800?
Inconel Alloy 800, (also referred to as Incoloy 800) is a nickel-iron-chromium alloy that was developed for service at high temperatures. This material exhibits excellent resistance to both oxidizing and carburizing conditions and maintains mechanical strength when exposed to high temperature service over time.
With this unique balance of chromium, nickel and iron contents, Alloy 800 works well in thermal cycling and in corrosive environments and in atmospheres which can cause carburization.
It is therefore common to find Incoloy 800 Bolts, and similar fasteners, used wherever extended, dependable service life is required.
