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 hex bar, at 0.15% for grade 200 against 0.02% for grade 201. Above all, that carbon gap decides how far this hex bar 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 hex bar.
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 hex bar.
| 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 hex bar 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 hex bar 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 hex bar.
Heat Treatment
Nickel 200 / 201 hex bar softens by annealing rather than by aging. We supply this hex bar 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 hex bar, issued by ASTM International. Moreover, ASME SB160 covers pressure equipment built from this hex bar, 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 |
| DIN 17752 | Nickel bar and rod, European procurement |
Finally, the full standards list on the Nickel 200 / 201 material page adds the European designations, the pressure-code documents and the forgings specification behind this hex bar.

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 hex bar before we release the order.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock giving this hex bar close diameter control and a smooth skin. |
| Peeled | A machined skin on this hex bar with uniform diameter for turning. |
| Rough Turned | A turned surface on this hex bar where the finishing cut comes later. |
Meanwhile, the surface finishes table on the Nickel 200 / 201 material page lists the remaining conditions we quote for this hex bar.

FAQ
Frequently Asked Questions
Which standard covers Nickel 200 / 201 Hex Bar?
ASTM B160 and ASME SB160 govern this hex bar 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 hex bar 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 hex bar enquiry.
Can this hex bar be machined and welded?
Yes. This hex bar machines to a clean finish, and GTAW with ERNi-1 filler joins it without difficulty.
How is the price of this hex bar calculated?
Pricing follows weight for this hex bar, with the nickel quotation fixed on the date you receive the offer.
What is your MOQ for this hex bar?
A single piece covers many common sizes of this hex bar.
What are your trade terms for this hex bar?
FOB covers most orders for this hex bar, and EXW or CIF terms are available when you ask.
What is the lead time for this hex bar?
Stock sizes of this hex bar 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 hex bar?
Yes. Every heat of this hex bar ships with 3.1, and a 3.2 endorsement is booked through the order.
What information should an enquiry for this hex bar include?
Please send grade, section, diameter, length, condition, finish, quantity and destination so we can quote this hex bar accurately.
