Composition and Key Features: Incoloy 800 hex bolts primarily consist of iron (Fe), nickel (Ni), and chromium (Cr), with trace amounts of other elements such as copper, titanium, and aluminum. This composition imparts several key features to these bolts:

  • High Temperature Resistance: Incoloy 800 hex bolts can withstand extreme temperatures, making them suitable for applications in furnace and heat exchanger components, petrochemical processing, and power generation.
  • Corrosion Resistance: The chromium content provides excellent resistance to oxidation and corrosion, even in highly aggressive environments, such as those containing sulfuric and nitric acids.
  • Mechanical Strength: These bolts exhibit good mechanical strength and dimensional stability at elevated temperatures, making them suitable for load-bearing applications in high-temperature environments.
  • Oxidation Resistance: Incoloy 800 hex bolts have the ability to form a protective oxide layer at high temperatures, further enhancing their resistance to corrosion.
