TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
UNS N02200 and N02201 share one nickel balance of 99.0% minimum, and the carbon ceiling alone separates the two grades inside this centreless-ground rod, at 0.15% for grade 200 against 0.02% for grade 201. Above all, that carbon gap decides how far this centreless-ground rod can run in hot service.
For an element-by-element account of every limit, open the composition breakdown held on the Nickel 200 / 201 material page for this centreless-ground rod.
Mechanical Properties
The minimum room-temperature values below apply to UNS N02200 and N02201 bar in the cold-worked, hot-worked and annealed conditions per ASTM B160. Condition and section size govern final acceptance of Nickel 200 / 201 centreless-ground rod.
| Condition and Section | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Nickel 200, cold-worked, rounds ≤ 25.4 mm (1 in.) | ≥80 ksi (550 MPa) | ≥60 ksi (415 MPa) | 10% |
| Nickel 200, cold-worked, rounds 25.4–101.6 mm (1–4 in.) | ≥75 ksi (515 MPa) | ≥50 ksi (345 MPa) | 15% |
| Nickel 200, cold-worked, squares, hexagons and rectangles | ≥65 ksi (450 MPa) | ≥40 ksi (275 MPa) | 25% |
| Nickel 200, hot-worked, all sections and sizes | ≥60 ksi (415 MPa) | ≥15 ksi (105 MPa) | 35% |
| Nickel 200, annealed, rods and bars of all sizes | ≥55 ksi (380 MPa) | ≥15 ksi (105 MPa) | 40% |
| Nickel 201, hot-worked, all sections and sizes | ≥50 ksi (345 MPa) | ≥10 ksi (70 MPa) | 40% |
| Nickel 201, annealed, all products and sizes | ≥50 ksi (345 MPa) | ≥10 ksi (70 MPa) | 40% |
- Elongation requirements do not apply to sections under 2.4 mm (3/32 in.), and the ordered condition together with the section size decides what the certificate states.
Physical Properties
Published references give this centreless-ground rod a density near 8.89 g/cm³ and a melting range of 1435–1446 °C. Moreover, the two grades part company on thermal conductivity, so design work on this centreless-ground rod starts from the grade actually ordered.
In addition, the physical properties table on the Nickel 200 / 201 material page carries the thermal conductivity, the electrical resistivity and the remaining design values behind this centreless-ground rod.
Heat Treatment
Nickel 200 / 201 centreless-ground rod softens by annealing rather than by aging. We supply this centreless-ground rod in the condition below that your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Annealed | Held between 705 and 925 °C (1300–1697 °F), then cooled |
| Stress Relieved | 705–870 °C (1300–1600 °F) where straightness or residual stress demands it |
| Custom Condition | Heat treatment according to the agreed specification |
Standards
ASTM B160 is the principal UNS N02200 and N02201 bar and rod document for this centreless-ground rod, issued by ASTM International. Moreover, ASME SB160 covers pressure equipment built from this centreless-ground rod, and no aerospace material specification reaches either grade.
| Standard | Product or Application |
|---|---|
| ASTM B160 | Nickel rod and bar, UNS N02200 and N02201 |
| ASME SB160 | ASME counterpart for pressure equipment |

Surface Finishes
Finish decides what happens at the next operation, whether that is a turning pass, a grinding pass or a welding cell. Specifically, we agree the finish on this Nickel 200 / 201 centreless-ground rod before we release the order.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled surface on this centreless-ground rod, for parts that will be machined all over. |
| Centreless Ground | Ground diameter and straightness on this centreless-ground rod for shafts and spindles. |
| Polished | Low roughness on this centreless-ground rod for product-contact and visible parts. |

FAQ
Frequently Asked Questions
Which standard covers Nickel 200 / 201 Centreless-Ground Rod?
ASTM B160 and ASME SB160 govern this centreless-ground rod for UNS N02200 and N02201 across round, square, hex and rectangular sections.
At what temperature should I order grade 201 instead of grade 200?
Above about 315 °C in continuous service, because grade 200 graphitizes there and grade 201 does not. Both grades suit cooler centreless-ground rod duty.
Is either grade suitable for wet hydrofluoric acid?
No. Wet hydrofluoric acid attacks both grades, so a copper-nickel alloy such as Monel 400 is the usual answer for that centreless-ground rod enquiry.
Can this centreless-ground rod be machined and welded?
Yes. This centreless-ground rod machines to a clean finish, and GTAW with ERNi-1 filler joins it without difficulty.
How is the price of this centreless-ground rod calculated?
Pricing follows weight for this centreless-ground rod, with the nickel quotation fixed on the date you receive the offer.
What is your MOQ for this centreless-ground rod?
A single piece covers many common sizes of this centreless-ground rod.
What are your trade terms for this centreless-ground rod?
FOB covers most orders for this centreless-ground rod, and EXW or CIF terms are available when you ask.
What is the lead time for this centreless-ground rod?
Stock sizes of this centreless-ground rod dispatch in 7 to 15 days, while made-to-order sections take longer.
Do you provide EN 10204 3.1 or 3.2 certificates for this centreless-ground rod?
Yes. Every heat of this centreless-ground rod ships with 3.1, and a 3.2 endorsement is booked through the order.
What information should an enquiry for this centreless-ground rod include?
Please send grade, section, diameter, length, condition, finish, quantity and destination so we can quote this centreless-ground rod accurately.
