Hastelloy C22 hex nuts are a type of fastener made from a high-performance nickel-based alloy known as Hastelloy C22, which is designated as UNS N06022. These nuts are widely recognized for their exceptional corrosion resistance and superior mechanical properties, making them a preferred choice in various demanding industrial applications, particularly in environments where exposure to aggressive chemicals is a concern.
Hastelloy C22 is part of the Hastelloy family, which was developed by Haynes International Inc. It contains a well-balanced composition of nickel, chromium, molybdenum, and tungsten, along with low levels of iron. These alloying elements contribute to the outstanding resistance of Hastelloy C22 to corrosion caused by a wide range of corrosive substances, such as acids, oxidizing chemicals, and reducing agents. This corrosion resistance is essential in industries like chemical processing, pharmaceuticals, and petrochemicals, where the integrity of fasteners is critical for safety and performance.
The hex shape of these nuts provides a convenient and secure method for tightening and loosening using common tools such as wrenches or socket sets. This makes them suitable for a wide range of applications, including pressure vessels, pipelines, pumps, and valves, where the nuts need to be securely fastened and easily maintained. Hastelloy C22 hex nuts are available in various sizes and thread specifications to accommodate diverse requirements.
