Inconel Fasteners

What are inconel fasteners?

Inconel fasteners are manufactured from a family of Nickel-Chromium superalloys known for their high strength, excellent oxidation resistance, and ability to maintain structural integrity at elevated temperatures, often well above 500°C. Their chemical composition may also include Iron, Molybdenum, Niobium or Aluminium, depending on the grade and performance requirement.

These properties make them a reliable choice for aerospace, nuclear, chemical processing, marine and high-temperature engineering applications, where creep resistance and corrosion protection are critical.

Which inconel grades are common?

We supply inconel fasteners in a range of grades, each offering different strengths:

• Inconel 600 (Alloy 600): Excellent mechanical stability and oxidation resistance, widely used in chemical processing.
• Inconel 625: High corrosion resistance and toughness, ideal for aggressive environments.
• Inconel 718: Designed for high strength and high-temperature performance, often used in aerospace.

Other grades (e.g. 601, 617, 690, 702 and more) are also available on request.

We supply a wide variety of inconel bolts, nuts, screws, washers and threaded bar, either from stock or manufactured to order in non-standard sizes, lengths, thread forms, and grades.
