Alloy 20 Flanges are specialized components made from the alloy known as Alloy 20, which is a nickel-iron-chromium-based super-austenitic alloy with excellent corrosion resistance. These flanges are designed to provide exceptional performance in a wide range of aggressive environments, making them suitable for use in industries where exposure to corrosive chemicals, acids, and extreme temperatures is common.

One of the key features of Alloy 20 Flanges is their remarkable corrosion resistance. The alloy's chemical composition includes approximately 32% nickel, 20% chromium, 3% molybdenum, 2% copper, and small amounts of niobium, which contribute to its resistance against various corrosive media, such as sulfuric acid, nitric acid, and phosphoric acid. Additionally, the alloy's high chromium content provides excellent resistance to pitting and crevice corrosion, further enhancing its reliability in challenging environments.

Alloy 20 Flanges undergo a specific heat treatment process to achieve their desired properties. They are typically annealed at temperatures around 1950°F to 2100°F (1065°C to 1150°C) followed by rapid cooling to ensure high strength and corrosion resistance.

Alloy 20 Flanges

Alloy 20 Flanges find applications in various industries where corrosion resistance is crucial. They are widely used in chemical processing plants for components such as reactors, heat exchangers, and storage tanks handling aggressive chemicals and acids. In the pharmaceutical industry, Alloy 20 Flanges are utilized in equipment exposed to corrosive substances. Additionally, they are employed in the food and beverage industry for equipment that comes into contact with acidic or corrosive solutions. Furthermore, Alloy 20 Flanges are used in petrochemical and oil refining industries, as well as in seawater handling systems due to their resistance to chloride-induced corrosion. Their versatility and reliability make them an essential choice for critical applications, ensuring the longevity and safety of equipment operating in highly corrosive and demanding conditions.
