Hastelloy C-2000 (UNS N06200 / W.Nr. 2.4675)
Hastelloy C-2000 (UNS N06200 / W.Nr. 2.4675) is unique among the versatile nickel-chromium-molybdenum materials in having a deliberate copper addition. This provides greatly enhanced resistance to sulfuric acid. It also has a high chromium content, to maximize its resistance to oxidizing chemicals and process streams contaminated with ferric ions and dissolved oxygen.

Features
- Designed to resist an extensive range of corrosive chemicals, including sulfuric, hydrochloric, and hydrofluoric acids
- Unlike previous Ni-Cr-Mo alloys, which were optimized for use in either oxidizing or reducing acids, C-2000 alloy extends corrosion resistance in both types of environments
- The combination of molybdenum and copper (at levels of 16 and 1.6 wt. %, respectively) provide the outstanding resistance to reducing media, while oxidizing acid resistance is provided by a high chromium content (23 wt. %).
Applications
- Chemical process industry reactors, heat exchangers, columns, and piping
- Pharmaceutical industry reactors and dryers
- Flue gas desulfurization systems
