Alloy 20 hex bolts are fasteners that are specifically designed for applications requiring exceptional resistance to corrosion and acidic environments. They are constructed from Alloy 20, a high-performance, nickel-iron-chromium alloy. These bolts have a hexagonal head, which allows for easy tightening and loosening with a wrench or socket.

One of the most notable properties of Alloy 20 is its resistance to a wide range of corrosive elements, such as sulfuric acid, phosphoric acid, nitric acid, and chloride solutions. This makes Alloy 20 hex bolts suitable for various industries, including chemical processing, petrochemical, pharmaceutical, and food processing.


The key features of Alloy 20 hex bolts include:

  • Corrosion Resistance: Alloy 20 is highly resistant to corrosion, making these bolts ideal for use in harsh environments where other materials might corrode or deteriorate rapidly.
  • Chemical Compatibility: They are compatible with a broad spectrum of chemicals and acids, ensuring they can withstand exposure to aggressive substances.
  • Temperature Resistance: Alloy 20 hex bolts maintain their strength and integrity at both high and low temperatures, making them suitable for a wide range of operating conditions.
  • Durability: These bolts are durable and have a long service life, reducing the need for frequent replacements.
  • Easy Installation: The hexagonal head design allows for easy and secure installation using common hand tools.
  • Versatility: Alloy 20 hex bolts are used in a variety of applications, including flanges, valves, and pressure vessels in industries where corrosion resistance is crucial.
