New Arvind Fastners & Fitings

Alloy 20 bolts are high-performance fasteners made from Alloy 20, a nickel-iron-chromium alloy known for its excellent corrosion resistance in harsh environments. These bolts are widely used in industries where strong resistance to chemical attack and excellent mechanical properties are required.

Key Features of Alloy 20 Bolts:

1. Corrosion Resistance:

   • Highly resistant to sulfuric acid, phosphoric acid, nitric acid, and other harsh chemicals.
   • Effective against chloride-induced stress corrosion cracking and pitting.

2. Mechanical Properties:

   • High strength and durability.
   • Excellent toughness at both ambient and elevated temperatures.

3. Applications:

   • Used in chemical processing, petrochemical, food, and pharmaceutical industries.
   • Ideal for environments with acid exposure, such as heat exchangers, storage tanks, and mixing tanks.

4. Standards and Specifications:

   • Common standards include ASTM B473, ASTM F2281, and ASTM B564.
   • Available in various sizes, lengths, and thread types.

5. Types of Bolts:

   • Hex bolts, stud bolts, carriage bolts, U-bolts, and anchor bolts, among others.
