What distinguishes C-2000
C-2000 belongs to the high-chromium, high-molybdenum nickel alloys. A deliberate copper addition distinguishes it from some related grades, particularly for sulphuric-acid service. Its applications extend across a range of chemical equipment.
The balance of chromium, molybdenum and copper
Chromium supports protection against oxidising chemicals. Molybdenum contributes to acid and localised chloride resistance, while copper complements its acid performance. Their combination explains the alloy’s use in both oxidising and non-oxidising chemicals.
Use in reactors and exchangers
Reactors and heat exchangers combine chemical exposure with temperature. C-2000 serves their wetted sections, acid piping and other process parts. Its principal purpose is a chemically resistant metal surface rather than exceptional hardness.

Relationship to C-22 and C-276
C-2000 is not another spelling of C-22 or C-276. All three serve corrosion applications but have different element limits. Copper is a prominent distinction for C-2000, identified separately by 2.4675 and N06200.
Typical application areas
Chemical reactors, heat exchangers, acid piping and process equipment.
