Hastelloy C2000
Description:
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
