Inconel Bolts, Screws, Nuts & Washers
Inconel Fasteners are made of Inconel, a group of Nickel-Chromium based superalloys typically chosen for their high working temperature range and corrosion resistance properties. Depending on the type or grade of Inconel, the chemical composition can include elements such as Iron, Molybdenum, Niobium and Aluminium – e specific properties.
These components provide good strength at room temperature due to the high levels of Chromium – retaining their strength at elevated temperatures exceeding 500°C. They offer excellent creep resistance that is often desired in extreme environments subject to increased heat and pressure e.g. aerospace and nuclear applications. Inconel forms a passivation layer at high temperatures, further increasing its resistance to corrosion.
Inconel 600, or Alloy 600, is one of most common grades of Inconel. It provides excellent mechanical properties and oxidation resistance – widely used in chemical processing applications as a result. Other common grades include Inconel 625 and Inconel 718 which are tailored towards corrosion resistance and high strength respectively.

Inconel Screws, Fasteners and Fixings
Inconel is an oxidation-resistant alloy with the ability to retain structural integrity in high temperatures.
There are a number of types of Inconel, including Inconel 600, 601, 617, 625, 690, 702, 706, 718, 800 and 903. Each variation has unique traits that are beneficial in a range of circumstances or applications.
The majority of these grades are used frequently as fasteners or fixings alongside chemicals as Inconel does not easily succumb to caustic corrosion, high purity water corrosion or stress-corrosion cracking.
Inconel 600 is a nickel-chromium alloy which is incredibly resistant to a number of corrosive elements – and it is often used in engineering as it is able to maintain its structure in applications that would cause permanent, irreversible distortion to other alloys.
Inconel 601 is very similar to 600, but has an addition of aluminium, which allows it to perform even in extremely high temperatures.
617 is an alloy consisting of nickel, chromium, cobalt and molybdenum, which is both corrosion and oxidation resistant. It is most often found in chemical processing due to a resistance to a wide range of corrosive liquids.
625 is a nickel-base alloy, and its properties include outstanding strength and toughness thanks to the addition of columbium and molybdenum.
Inconel 690 is a high chromium-nickel alloy with high strength and good fabrication characteristics.
