Hastelloy C22 is a nickel-chromium-molybdenum-tungsten alloy with outstanding resistance to a variety of aggressive chemicals, including oxidizing and reducing environments. Hastelloy C22 wires are a popular form of this alloy and are widely used in various industrial applications.
Chemical Composition: Hastelloy C22 wires typically contain nickel as the major component, along with chromium, molybdenum, tungsten, and a small amount of iron. The alloy's composition provides it with exceptional corrosion resistance in both oxidizing and reducing conditions.
Corrosion Resistance: One of the primary reasons for the popularity of Hastelloy C22 wires is their exceptional corrosion resistance. They are highly resistant to corrosion by a wide range of chemicals, including chlorides, sulfuric acid, hydrochloric acid, acetic acid, and phosphoric acid. This makes them suitable for use in harsh chemical processing environments.
