Hastelloy C-22 UNS N06022 W.Nr.2.4602 Bar / Rod / Wire / Forging / Plate / Strip Suitable For High-temperature In Scrubbers
Hastelloy C-22 (UNS N06022, W.Nr. 2.4602) is a versatile nickel-chromium-molybdenum alloy known for exceptional resistance to corrosion, particularly in oxidizing and reducing environments. Its high resistance to pitting, crevice corrosion, and stress corrosion cracking makes it ideal for harsh chemical processing. Bar, rod, and wire are used in components like shafts, fasteners, and welding electrodes. Forgings are employed in custom parts for reactors, valves, and pressure vessels. Plate and strip are used for cladding, heat exchangers, and corrosion-resistant linings. Common industries include chemical processing, pollution control, and aerospace. C-22’s outstanding weldability and resistance to a wide range of acids make it a preferred choice in demanding environments.
