Hastelloy C22 and Hastelloy C276 Flanges are specialized components made from two different variants of the Hastelloy family of nickel-chromium-molybdenum alloys. Both alloys are designed to offer exceptional corrosion resistance in highly aggressive environments, making them suitable for use in industries where exposure to corrosive chemicals, acids, and extreme conditions is prevalent.

Hastelloy C22 Flanges are crafted from the alloy Hastelloy C22, which is renowned for its outstanding resistance to a wide range of corrosive media, including sulfuric acid, hydrochloric acid, acetic acid, and seawater. The flanges' high chromium content (approximately 22%), along with molybdenum and tungsten additions, provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Hastelloy C22 is a versatile alloy used in various industries, such as chemical processing, pharmaceuticals, and pulp and paper, where its corrosion resistance and reliability are vital for handling aggressive chemicals.

Hastelloy C276 Flanges, on the other hand, are made from the alloy Hastelloy C276, which offers even broader corrosion resistance than Hastelloy C22. The alloy's chemical composition includes approximately 57% nickel, 16% chromium, 16% molybdenum, and small amounts of tungsten and iron. Hastelloy C276 exhibits exceptional resistance to a wide range of corrosive environments, including strong acids, chlorine, and oxidizing and reducing media. Due to its superior corrosion resistance, Hastelloy C276 Flanges find applications in various industries, such as chemical processing, power generation, and pollution control, where exposure to aggressive chemicals and harsh conditions is common.

Both Hastelloy C22 and Hastelloy C276 Flanges undergo suitable heat treatment to achieve their desired properties. They are typically solution annealed at temperatures between 2025°F to 2100°F (1100°C to 1150°C), followed by rapid cooling to ensure high strength and corrosion resistance.

 Hastelloy C276 Flanges

These flanges find widespread applications in industries where corrosion resistance is paramount. In chemical processing plants, they are used for various components, such as reactors, heat exchangers, and valves, which handle corrosive chemicals. In the pharmaceutical industry, Hastelloy Flanges ensure the integrity of equipment used in processing aggressive substances. Additionally, they are employed in power generation facilities, where they resist the corrosive effects of flue gas and other byproducts. In pollution control equipment, these flanges are essential for withstanding harsh environments. Both Hastelloy C22 and C276 Flanges have proven to be reliable components in critical applications, ensuring the longevity and safety of equipment operating in highly corrosive and challenging conditions.
