About Inconel 718 Fasteners

The Inconel 718 fasteners are designed to provide superior strength at high temperatures of up to 1800°F (982°C ). This is done by precipitation hardening and a high level of nickel and chromium. The Inconel 718 fasteners are composed of nickel-chromium alloy with 58-63% nickel, 20-23% chromium and 8-10% molybdenum to ensure durability and corrosion and pitting resistance. Boron, phosphorus, sulfur, silicon and titanium are some of the elements that will increase their mechanical and chemical properties. All these attributes render Inconel 718 fasteners resistant to corrosive gases, including hydrogen sulfide (H2S ) and carbon dioxide (CO2 ), and make them applicable in chemical processing, natural gas plants, among other industrial applications.

The fasteners made of Inconel 718 have numerous types such as Werkstoff Nr. 2.4668 U bolts, AISI Inconel 718 hex nuts, ASME SB637 grade 718 stud bolts, ASTM B637 Inconel 718 threaded rods, UNS N07718 spring washers and DIN 2.4668 heavy hex nuts that are designed to work with high levels of torque. The types of threads available in Inconel 718 bolts include a wide variety of threads, including BSW, UNC, UNF, BSF, and metric threads. They can be coated with zinc, black, passivated stainless steel, Teflon, cadmium, hot-dip galvanizing or xylon to give even greater resistance to corrosion. Minimum yield strength of these fasteners is 170 ksi and tensile strength is 202 ksi and also they are strong even in cryogenic conditions up to a minimum of 1300 °C. ASME B18.5, ANSI B28.2.4-1 M and ASTM B637 and DIN 2.4668 are some of the standards under which the Inconel 718 fasteners are produced. Its products are. The creep rupture strength of Inconel 718 fasteners is high and they can resist chemical corrosion making them very reliable even in the most industrial uses.

Frequently Asked Questions About Inconel 718 Fasteners

What are Inconel 718 bolts used for?

Inconel 718 bolts are used in high-temperature, high-pressure, and corrosive environments. They are commonly used in aerospace engines, gas turbines, oil & gas equipment, nuclear reactors, chemical plants, and marine applications. Their strength and stability make them ideal for critical, heavy-duty operations.

Is Inconel 718 a type of stainless steel?

No. Inconel 718 is a nickel-based superalloy, not stainless steel. It contains high nickel, chromium, and niobium, which give it superior heat resistance, strength, and corrosion resistance far beyond what stainless steel can offer. This makes it suitable for extreme working conditions.

What thread types are available for Inconel 718 fasteners?

Inconel 718 fasteners can be supplied in a variety of thread types, including:

 

  • UNC / UNF (Unified National Coarse & Fine
  • Metric Threads (M Series)
  • BSW / BSP (British Threads)
  • ACME Threads
  • NPT Threads
What temperatures can Inconel 718 fasteners withstand?

Inconel 718 fasteners can handle temperatures from -250°C to around 700°C while retaining strength and corrosion resistance. They also resist oxidation and scaling at elevated temperatures.

Are Inconel 718 fasteners suitable for marine and offshore use?

Yes. Inconel 718 fasteners perform very well in seawater, salt spray, and high-chloride conditions due to their excellent corrosion resistance. They are widely used in submarines, offshore drilling platforms, and marine turbines.

Can Inconel 718 fasteners be customized?

Yes. They can be manufactured in custom sizes, lengths, thread types, coatings, and head styles based on project requirements. MTC, third-party inspection, and special testing can also be provided.
