Alloy 20 Stud Bolts are fasteners made from a special alloy known as Alloy 20, which is also referred to as Carpenter 20. This alloy is a nickel-iron-chromium-based material with additions of copper and molybdenum. Alloy 20 stud bolts are designed to provide exceptional corrosion resistance in a wide range of aggressive environments, making them highly sought after in industries such as chemical processing, pharmaceuticals, and petrochemical.

Key features and benefits of Alloy 20 stud bolts:

Corrosion Resistance: One of the primary advantages of Alloy 20 stud bolts is their remarkable resistance to corrosion, especially in acidic and corrosive environments. They are highly resistant to sulfuric acid, phosphoric acid, and nitric acid, making them ideal for chemical processing plants and other industries where corrosive substances are present.

Chloride Stress Corrosion Cracking: Alloy 20 is particularly well-suited for use in chloride-containing environments. It resists chloride stress corrosion cracking, a common problem in many stainless steel alloys.

High Temperature Resistance: Alloy 20 stud bolts maintain their integrity and strength at elevated temperatures. This attribute is valuable in applications that involve high-temperature operations, such as in heat exchangers and reactors.

Mechanical Strength: These stud bolts provide good mechanical properties, including high tensile strength, which is crucial for securely fastening components in various industrial settings.
