Incoloy Fasteners stand as indispensable elements renowned for their remarkable performance under the most demanding conditions. Fabricated from the robust superalloy Incoloy, they exhibit excellent resistance to extreme temperatures, oxidation, and corrosive environments. Their exceptional durability and reliability make them vital components across industries such as aerospace, chemical processing, and oil and gas, where standard fasteners falter. Serving as crucial guardians of structural integrity, Incoloy fasteners play a pivotal role in fortifying assemblies and ensuring the sustained operation of vital systems, even amidst the harshest operational challenges.

We offer These Incoloy Fasteners as per DIN, ISO, JIS or ANSI Standard.
Incoloy fasteners find widespread industrial applications due to their exceptional properties. Their high resistance to corrosion, even in aggressive environments, makes them invaluable in industries such as chemical processing, offshore drilling, and marine engineering, where exposure to corrosive substances is common. Their ability to maintain mechanical integrity at elevated temperatures makes them indispensable in the aerospace, automotive, and power generation sectors.
Yes, Incoloy fasteners can be welded using conventional welding techniques such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). However, proper welding procedures and filler materials compatible with the specific Incoloy grade are essential to maintain the material’s corrosion resistance and mechanical properties.
Yes, Incoloy fasteners are suitable for hygienic and sanitary applications in industries such as food processing and pharmaceuticals. Their corrosion resistance and ability to withstand high temperatures make them ideal for environments requiring frequent cleaning and sterilization, ensuring compliance with strict hygiene standards.
Incoloy fasteners can be susceptible to galvanic corrosion when in contact with dissimilar metals in corrosive environments. Proper selection of compatible materials and insulation methods, such as using isolation washers or coatings, can mitigate the risk of galvanic corrosion and ensure the longevity of the fasteners.
Yes, certain grades of Incoloy alloys, such as Incoloy 825, are suitable for cryogenic applications due to their excellent mechanical properties and resistance to low temperatures. They maintain their strength, toughness, and corrosion resistance at cryogenic temperatures, making them suitable for use in liquefied natural gas (LNG) storage tanks and aerospace applications.
