Hastelloy C-2000 (Alloy C-2000), designated as UNS N06200 and W.Nr. 2.4675, is a corrosion-resistant nickel-chromium-molybdenum-copper alloy. It offers outstanding resistance to a broad range of aggressive chemicals, including strong oxidizers and reducing acids like hydrochloric, sulfuric, and nitric acid—making it one of the most versatile Hastelloy grades available.
Hastelloy C-2000 is widely used in chemical processing, waste treatment, and pharmaceutical production. Its superior corrosion performance and mechanical strength make it ideal for reactors, pressure vessels, piping systems, heat exchangers, and scrubbers exposed to harsh chemical environments.
