Incoloy 800/800H/800HT Fasteners Uses

Application Industry

Incoloy 800/800H/800HT Fasteners are used across a broad range of industrial applications thanks to their outstanding characteristics. Their strong resistance to corrosion, even under harsh conditions, renders them essential in sectors like chemical processing, offshore drilling, and marine engineering, where contact with corrosive materials is frequent. Because they can retain their mechanical strength at high temperatures, they are crucial in the aerospace, automotive, and power generation industries.

Aerospace Industry

Automotive Industry

Petro Chemical Industry

Power Generation Industry

Petrochemical Industry: Fasteners produced from these alloys are widely employed in reactors, heat exchangers, piping systems and other equipment within petrochemical plants that involve high temperatures and corrosive chemicals.
Power generation: Thanks to their high thermal conductivity and their resistance to oxidation and vapour, Incoloy fasteners are used in power generation, particularly in boilers and steam turbines where high temperatures and pressures occur
Chemical applications: Incoloy binders serve chemical plants that rely on vapour and high-temperature chemicals for treating vessels, pipelines and other equipment where corrosion resistance and high-temperature operation are essential
Aerospace Applications: For aerospace uses in which parts face high temperatures during flight or manufacturing, Incoloy binders are chosen because of their strong thermal properties and thermal resistance

How to Choose the Right Incoloy 800/800H/800HT Fasteners

Temperature Requirements: Indicate the highest operating temperature for your application. Compared to Incoloy 800, Incoloy 800H and 800HT deliver greater creep-rupture strength when temperatures rise. Choose the alloy that best fits your application’s temperature requirements.
Corrosion Resistance: Assess the corrosion condition of your binders. Incoloy 800 Series alloys deliver outstanding resistance to oxidation and carburization in high-temperature settings, along with corrosion resistance across many acidic and alkaline environments. Take into account the particular chemicals present and choose an alloy with the corrosion resistance needed.
Mechanical properties: Take into account key mechanical properties for your fasteners, including tensile strength, yield strength, and elongation. Incoloy 800H and 800HT generally show higher efficiencies than Incoloy 800, which makes them well suited for applications that demand more machining.

Can Incoloy 800/800H/800HT Fasteners be welded?

Yes,Incoloy 800/800H/800HT fasteners are weldable through suitable welding methods and filler metals designed for high-temperature alloys. Care should be taken to prevent heat-affected zone (HAZ) problems and to preserve the alloy’s corrosion resistance throughout the welding process.

FAQ (Frequently Asked Questions)

Are Incoloy 800/800H/800HT Fastener suitable for hygienic and sanitary applications?

Incoloy 800/800H/800HT fasteners might not be the best choice for hygienic and sanitary applications because their high-temperature strength and oxidation resistance can be excessive for such settings. For hygienic and sanitary applications, stainless steel fasteners offering superior corrosion resistance and cleanliness standards are generally the preferred option.

Are Incoloy 800/800H/800HT Fasteners susceptible to galvanic corrosion?

Incoloy 800/800H/800HT fasteners can be prone to galvanic corrosion when they come into contact with dissimilar metals in corrosive environments. To avoid galvanic corrosion, which results from the electrical potential difference between the metals, it is essential to use proper insulation or choose compatible materials.

Are Incoloy 800/800H/800HT Fasteners suitable for cryogenic applications?

Incoloy 800/800H/800HT fasteners are typically not advised for cryogenic applications because of their reduced mechanical properties and susceptibility to embrittlement at low temperatures. In cryogenic environments, materials engineered specifically for cryogenic service, like stainless steels or nickel-based alloys offering low-temperature stability, are the preferred choice.
