What is Hastelloy C-2000?
Hastelloy C-2000 (N06200, 2.4675, NiCr23Mo16Cu) is a Ni-Cr-Mo alloy with a copper addition, combining high chromium for oxidizing acids with high molybdenum for reducing acids, including sulfuric and hydrochloric. Solution-annealed sheet, plate, bar and tube provide 355 MPa yield, 760 MPa tensile, 62% elongation, 88 HRB, corrosion score 93 and formability score 78. It machines poorly (score 18) and costs more than C-276 and C-22, which remain adequate unless resistance in oxidizing acids is the controlling requirement. Hastelloy C-2000 has a density of 8.5 g/cm³ (0.307 lb/in³), heavier than 64% of nickel alloy grades. It melts at 1,328°C (2,422 °F). Hastelloy C-2000 has a yield strength of 355 MPa (51.5 ksi) and a tensile strength of 760 MPa (110 ksi) — weaker than 59% of nickel alloy grades. Elongation at break is 62% and the elastic modulus is 207 GPa (30 Msi).

Working with Hastelloy C-2000
Is Hastelloy C-2000 easy to machine?
Machine like C-276/C-22: rigid setup, positive-rake sharp carbide, low speed with heavy feed and flood coolant; never dwell, as the alloy work-hardens instantly.
Can Hastelloy C-2000 be welded?
Readily GTAW/GMAW/SMAW welded with matching ERNiCrMo-17 filler; keep interpass below ~120 °C, low heat input, no preheat or PWHT needed, and clean/pickle to restore the passive film.
Can Hastelloy C-2000 be formed, bent or molded?
Very ductile but high yield-to-flow force — form cold with 2× the power used for stainless, and re-solution anneal at ~1120 °C with rapid quench after heavy cold work.
Hastelloy C-2000 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |

| Cr | 22 – 24 | 23 |
| Mo | 15 – 17 | 16 |
| Cukey addition for reducing-acid resistance | 1.3 – 1.9 | 1.6 |

| P | ≤ 0.03 | |
| S | ≤ 0.01 | |
| Nibalance, nominally ~59 % | balance |
What surface finishes work on Hastelloy C-2000?
Not anodizable; grind/blast then pickle or electropolish and passivate for maximum acid resistance — avoid iron contamination from carbon-steel tooling.

Hastelloy C-2000 — frequently asked
What is Hastelloy C-2000 used for?
Hastelloy C-2000 is typically used for chemical processing equipment, sulfuric acid production, pollution control scrubbers, pharmaceutical reactors and flue-gas desulfurization. In short: mixed-acid nickel alloy; better oxidizing resistance than C-276; very ductile, 62% elongation.
What is the yield strength of Hastelloy C-2000?
Hastelloy C-2000 has a typical yield strength of 355 MPa (51.5 ksi) and a tensile strength of 760 MPa (110 ksi) — weaker than 59% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is Hastelloy C-2000 easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Machine like C-276/C-22: rigid setup, positive-rake sharp carbide, low speed with heavy feed and flood coolant; never dwell, as the alloy work-hardens instantly.
Can Hastelloy C-2000 be welded?
Yes — weldability is rated excellent (85/100). Readily GTAW/GMAW/SMAW welded with matching ERNiCrMo-17 filler; keep interpass below ~120 °C, low heat input, no preheat or PWHT needed, and clean/pickle to restore the passive film.
What surface finishes work on Hastelloy C-2000?
Not anodizable; grind/blast then pickle or electropolish and passivate for maximum acid resistance — avoid iron contamination from carbon-steel tooling.
Can Hastelloy C-2000 be formed, bent or molded?
Very ductile but high yield-to-flow force — form cold with 2× the power used for stainless, and re-solution anneal at ~1120 °C with rapid quench after heavy cold work.
What is the maximum service temperature of Hastelloy C-2000?
Hastelloy C-2000 is rated for continuous use to about 700°C (1,292 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Hastelloy C-2000-SA and Hastelloy C-2000-CD?
SA is the default condition — standard supplied condition for all wrought forms; maximum corrosion resistance and ductility. CD: pick when higher strength and hardness are needed and full anneal-level corrosion resistance is not critical. Yield strength is 355 MPa in SA versus 690 MPa in CD.
How much does Hastelloy C-2000 cost?
Hastelloy C-2000 is a high-cost nickel alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
