Incoloy 800 Hex Nuts is a nickel-iron-chromium alloy with molybdenum and copper added, known for its excellent resistance to a variety of corrosive environments. UNS N08800 is the Unified Numbering System designation for this particular alloy. It offers high corrosion resistance in both reducing and oxidizing environments, making it particularly suitable for applications in chemical processing, petrochemical industry, and marine environments.
Hex nuts made from Incoloy 800 (UNS N08800) are used in various applications where corrosion resistance and high-temperature strength are required. These nuts are designed to be compatible with Incoloy 800 bolts or other fasteners made from the same material. They provide a secure and reliable fastening solution in aggressive and demanding environments.
Here are some key features and applications of Incoloy 800 hex
nuts:
Corrosion Resistance: Incoloy 800 hex nuts exhibit outstanding
resistance to various corrosive media, including sulfuric acid, phosphoric acid,
nitric acid, and seawater.
High-Temperature Strength: They maintain their mechanical
properties at elevated temperatures, making them suitable for high-temperature
applications.
Excellent Weldability: Incoloy 800 can be readily welded and
used in combination with other materials.
Good Mechanical Properties: This alloy offers good strength and
durability.

Applications:
Chemical Processing: Incoloy 800 hex nuts are commonly used in
chemical plants, where they come into contact with corrosive chemicals and
acids.
Oil and Gas Industry: They find applications in the oil and gas
sector, including offshore drilling platforms, due to their resistance to
seawater and other aggressive environments.
Pollution Control Equipment: Incoloy 800 is used in pollution
control equipment where resistance to acid gases and other pollutants is
required.
Heat Exchangers: It is employed in heat exchangers for its
resistance to high-temperature and corrosive conditions.
