Incoloy 825 Nuts

Manufacturer of ASTM F467 UNS N08825 Eye Nut in India

Inconel 825 Nuts are among the most renowned and widely used in aerospace, chemical processing, and marine engineering. They are made of a nickel-chromium alloy with added molybdenum, copper, and titanium that enhance their strength, resistance to heat, and corrosion. Inconel 825 nuts are available in a variety of types. Some of the most common Inconel 825 Nuts include Hex , Flange, Jam, Wing, Coupling, etc. Hex nuts are the most widely used type of Inconel 825 nuts. They are six-sided and used with bolts and other similar hardware. An Inconel 825 nut that can prevent loosening due to vibrations, then Jam nuts should be the go-to option. Similarly, Flange nuts come with a flared base that enhances the strength of the fastening system.


The strength and durability of Inconel 825 Nuts make them popular among various industries. In aerospace, Inconel 825 nuts hold aircraft engine parts together. Inconel 825 nuts resist corrosive environments such as sulfuric and hydrochloric acids in the chemical processing industry. In marine engineering, these nuts are used on subsea pipelines and offshore drilling rigs.


Inconel 825 nuts have a multitude of benefits. They are strong and highly resistant to corrosion. They can withstand harsh chemical environments and high temperatures and have excellent mechanical properties. Their ability to withstand corrosion is especially important in the chemical and oil and gas industry, where exposure to harsh chemicals is ubiquitous. Inconel nuts are also bio-compatible, making them ideal for medical applications. They have excellent fatigue resistance, which makes the fastening system secure and reduces the chances of loosening under vibration.


Inconel 825 nuts are reliable and durable for those requiring top-notch fasteners. Their excellent corrosion resistance and mechanical properties make them perfect for use in the aerospace, chemical processing, marine engineering, and medical industries. Their use means high strength, longevity, and reliable fastening that will increase the safety and efficiency of fastening systems. The Inconel 825 nuts include Hex, Flange, Jam, Wing, Coupling, and many other options to meet specific needs.
