Understanding the Concept of Alloy 20 Stud Bolt

What are Alloy 20 Stud Bolts?

Alloy 20 stud bolts are made from a high-performance material known as Alloy 20, an austenitic nickel-iron-chromium alloy with molybdenum, copper, & nitrogen additions. 

It’s known for its excellent resistance to corrosion, acidic environments, and stress corrosion cracking. Alloy 20 Stud Bolts connect two separate parts or components, relying on the pressure between them to ensure they stay securely in place.

Applications of Alloy 20 Stud Bolts

Alloy 20 stud bolts are used in different applications across various industries. They’re commonly found in offshore oil and gas applications, chemical processing plants, pharmaceutical industries, food & beverage production. 


They’re also used in acid storage tanks, heat exchangers, pumps, piping, and valves. They’re suitable for use in harsh environments with high temperatures, acidic solutions, & corrosive materials.

Advantages of Alloy 20 Stud Bolts

One of the significant advantages of Alloy 20 stud bolts is their excellent corrosion resistance. They offer superb resistance to chloride-induced stress corrosion cracking, sulfuric acid, and other organic acids. They’re also highly resistant to pitting & crevice corrosion. 


They have high mechanical strength, which makes them suitable for high-pressure applications. They’re also highly durable and require little maintenance. They can be easily fabricated and welded, which makes them versatile & flexible in use.
