Hastelloy

Hastelloy is a family of nickel-based superalloys known for their exceptional resistance to corrosion, high-temperature strength, and excellent mechanical properties. These alloys are designed to withstand highly corrosive environments, making them widely used in industries such as chemical processing, oil and gas, aerospace, and pollution control. Hastelloy alloys are composed primarily of nickel, with significant additions of chromium, molybdenum, and other elements such as iron, cobalt, tungsten, and copper. The specific composition varies depending on the grade of Hastelloy alloy and its intended application.

Common Grades of Hastelloy Alloys

Hastelloy C-276: This alloy offers excellent resistance to corrosion in a wide range of aggressive media, including strong acids, chlorides, and sulfuric environments. It has good mechanical properties and is used in chemical processing equipment, pollution control systems, and seawater applications.

Hastelloy C-22: Known for its versatility and outstanding resistance to both oxidizing and reducing environments, Hastelloy C-22 is used in various corrosive applications such as chemical reactors, pickling equipment, and flue gas desulfurization systems.

Hastelloy X: This alloy exhibits high-temperature strength and oxidation resistance. It is commonly used in gas turbine engines, industrial furnace components, and aircraft engine afterburners.

Hastelloy alloys offer excellent resistance to corrosion, pitting, crevice corrosion, and stress corrosion cracking. They maintain their mechanical properties at high temperatures and possess good weldability.
