R60001 is nuclear-grade zirconium, a reactive metal with a controlled low hafnium content. This datasheet presents the material within the American (ASTM / ASME / UNS) standard system.
Zirconium is a reactive metal noted for outstanding corrosion resistance and, in nuclear grades, a very low thermal-neutron-capture cross-section. R60001 is a nuclear-grade zirconium with a controlled maximum hafnium content (typically below 0.010%), making it suitable for nuclear-reactor core structural applications where neutron economy is critical. It combines low neutron capture with good corrosion resistance in high-temperature water and steam, good ductility and weldability, and is supplied in the annealed condition.
Typical applications include nuclear-reactor core structural components and hardware where low neutron capture and corrosion resistance in reactor coolant are required.

Confirm against the mill test report. Strength depends on oxygen content and condition.
| Environment | Performance | Notes |
|---|---|---|
| Reactor coolant water / steam | Excellent | Low corrosion + low neutron capture |
| High-temperature water | Excellent | Core structural service |
| Sulfuric acid (≤70%) | Excellent | Resistant; attacked at high conc. |
| Strong alkalis | Excellent | Resists hot caustic |
| Ferric / cupric chlorides, aqua regia | Poor | Attacked; also HF |
Zirconium offers outstanding resistance to hydrochloric and nitric acids, hot caustic and many organic acids through a self-healing oxide film, but is attacked by hydrofluoric acid, ferric and cupric chlorides, wet chlorine and aqua regia.
A reactive metal; not hardenable by precipitation. Properties are governed by working and annealing.
Anneal Anneal in vacuum or a protective atmosphere at approximately 540–815 °C to recrystallise and restore ductility after cold work. Avoid oxygen, nitrogen and hydrogen pickup, which embrittle the metal; pickling removes surface contamination.
Excellent weldability by inert-gas processes; the weld and hot metal must be fully shielded from air (trailing shields, backing gas or chambers), because oxygen, nitrogen and hydrogen pickup cause embrittlement.
| Welding Process | Applicability | Notes |
|---|---|---|
| GTAW / TIG | Excellent | Full inert shielding / trailing shield |
| GMAW / MIG | Good | Matching filler |
| EBW / plasma | Good | Vacuum or high-purity shielding |
Weld under full inert-gas shielding with clean surfaces; a bright, silvery weld indicates good shielding, while colours indicate contamination.
Machining Guidelines
| Parameter | Recommendation |
|---|---|
| Machinability | Fair; sharp tooling, slow speeds, heavy feeds |
| Caution | Fine chips/dust are pyrophoric — manage swarf, flood coolant |
| Coolant | Ample non-chlorinated coolant |
