Working with Hastelloy C-2000-SA
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.
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-SA — frequently asked
What is Hastelloy C-2000-SA used for?
Hastelloy C-2000-SA 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-SA?
Hastelloy C-2000-SA 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-SA 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-SA 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-SA?
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-SA 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-SA?
Hastelloy C-2000-SA 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.
