We offer These Incoloy 800/800H/800HT Fasteners as per DIN, ISO, JIS or ANSI Standard.
Incoloy 800/800H/800HT 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 800/800H/800HT fasteners can be welded using appropriate welding techniques and filler materials suited for high-temperature alloys. Precautions must be taken to avoid heat-affected zone (HAZ) issues and maintain the corrosion resistance of the alloy during welding.
Incoloy 800/800H/800HT fasteners may not be ideal for hygienic and sanitary applications due to their high-temperature strength and oxidation resistance, which can be overkill for such environments. Stainless steel fasteners with better corrosion resistance and cleanliness standards are typically preferred for hygienic and sanitary applications.
Incoloy 800/800H/800HT fasteners may be susceptible to galvanic corrosion when in contact with dissimilar metals in corrosive environments. Proper insulation or selection of compatible materials is crucial to prevent galvanic corrosion, which occurs due to the electrical potential difference between the metals.
Incoloy 800/800H/800HT fasteners are generally not recommended for cryogenic applications due to their diminished mechanical properties and potential for embrittlement at low temperatures. Materials specifically designed for cryogenic service, such as stainless steels or nickel-based alloys with low-temperature stability, are preferred in cryogenic environments.
