Hastelloy C-2000 (UNS N06200) — Composition, Properties & Supply
Hastelloy C-2000 (UNS N06200) adds about 1.6% copper and raises chromium to 22–24% while keeping 16% molybdenum. It is the only C-family alloy that spans both oxidising acids (nitric) and reducing acids (sulphuric, hydrochloric), giving the widest universality.

Frequently asked questions
What service suits C-2000 best?
C-2000 suits processes where the medium changes frequently and one vessel must handle several acids — multi-product fine-chemical reactors, mixed-acid pickling lines and acid recovery units. If exposure is a single, stable medium, C-276 (reducing) or C-22 (oxidising) is usually more economical.
