Nickel 200 / 201 Round Bar
Solid rounds from 6 to 500 mm for caustic plant shafts, sleeves and machined parts.
View Nickel 200 / 201 Round Bar →Commercially pure nickel bar and rod for caustic handling and chemical processing equipment.
Hot-worked, cold-worked, and annealed bar quote against the same specification, so one order covers several machining steps.
Also, round, square, hex, flat, and forged sections come from one enquiry, which keeps a fabricated assembly on one stock list.
Finally, bright drawn, peeled, and centreless-ground bar arrive at the diameter your automatic machines expect.
Nickel 200 / 201 bar and rod come in two commercially pure nickel grades. They share one chemistry, and the carbon limit alone separates them.
B160 governs both grades across every section. The Nickel 200 / 201 material page holds the full grade data, while Nickel 200 / 201 Pipe and Tube and Nickel 200 / 201 Plate and Sheet cover the other two forms.
Section size and condition decide the strength a buyer receives. Cold-worked rounds run stronger than annealed stock, and elongation moves the other way. Therefore, we confirm both the drawing and the machining step before quoting a diameter.
Southerly Alloy works as a professional supplier and exporter for both grades in bar and rod. We keep one contact on the file, so the same person answers technical questions and handles the shipping papers.
Nickel 200 and Nickel 201 bar and rod serve machined parts that meet caustic, reducing, and alkaline media, and the same sections carry current and heat. Section size and delivery condition decide the strength level, since cold-worked bar runs stronger than annealed stock. Southerly Alloy works as a professional supplier and exporter for both grades in round, square, hex, flat, and forged sections to ASTM B160, with EN 10204 3.1 documentation.
Sodium hydroxide and potassium hydroxide at every concentration sit inside the envelope, and molten alkali salt does too.
Moreover, neutral and alkaline salt solutions bring no stress-corrosion cracking, which suits pump and valve parts.
In addition, the grades machine to a clean finish and hold dimension in service, so fitted parts keep their clearance.
Cold-worked rounds reach 550 MPa tensile, which serves shafting without a heat treatment step.
Furthermore, both grades stay magnetic below a Curie point near 360 °C, which serves solenoid and switching parts.
The 0.02% carbon cap removes graphitization, so parts above 315 °C call for the low-carbon grade.
Similarly, round, square, hex, flat, and forged sections share one composition table and one certificate set.
Wet hydrofluoric acid and oxidizing acids sit outside the envelope, and grade 201 meets sulfide attack above 315 °C.
Four points shape a bar and rod order. They cover the sections we quote, the condition and finish on offer, the documents that follow the heat, and export handling.
First, round, square, hex, flat, and forged sections quote together, so a machine shop orders once.
We match hot-worked, cold-worked, or annealed stock to the operation that follows, and the certificate states what shipped.
Also, EN 10204 3.1 paperwork, heat numbers, and PMI records travel with the bar rather than trailing the delivery.
We cut to your length or supply random lengths, whichever keeps your saw and your scrap budget happy.
Bar production follows a fixed route from heat to packed bundle. Meanwhile, the ordered section and condition decide how many working and annealing steps apply.
Nickel cathode and controlled additions go to the N02200 or N02201 chemistry, with carbon inside the ordered limit.
A controlled atmosphere limits gas pickup as the heat casts into ingots.
Ingots reduce to bloom or bar at temperature, and the reduction refines the cast structure.
A machined skin removes surface defects before the finishing passes begin.
Drawing brings cold-worked bar to its final diameter, tolerance, and surface.
Heat treatment restores ductility where the order names the annealed condition.
The line straightens, squares, and cuts bar to the ordered length.
Chemistry, tensile properties, and dimensions pass review against the purchase specification.
Standard sections and made-to-order diameters leave against one schedule. Both grades work to the same delivery dates, and cut length and finish are settled before production starts. Therefore, a mixed order ships as a single consignment.
Melting, forging, drawing, and inspection halls sit on one site.
Forging presses, draw benches, and grinding lines serve the bar route.
Nickel and nickel alloy bar output in stock and custom sizes.
Metallurgists match condition and finish to the machining step.
Hot-worked, cold-worked, and annealed bar cover most drawings.
Custom sections run about that long after confirmation.
Release happens on the heat, and no bundle leaves the yard before that point. Consequently, our inspection covers chemistry, mechanical properties, and dimensions against the purchase specification.
We check every heat for the N02200 or N02201 balance before the bar enters production.
Next, diameter, straightness, and length go against your drawing and the applicable tolerance.
Then tensile, yield, and elongation come from the ordered condition, and we add hardness on request.
Finally, certificates, heat numbers, and PMI results follow the bar through dispatch.
Round bar and rod carry most Nickel 200 / 201 enquiries, while hex, square and flat sections serve frames. Cold-drawn, ground, threaded and forged routes each hold their own tolerance band. Every form below is quoted on its own condition and finish.

B160 carries the composition table for both grades, and nickel comes by difference with cobalt included. Grade 200 permits up to 0.15% carbon, while grade 201 holds that element to 0.02%. An ordered specification and its certificate decide acceptance.
| Element | Nickel 200 (UNS N02200) | Nickel 201 (UNS N02201) |
|---|---|---|
| Nickel (Ni), min. | 99.0% | 99.0% |
| Copper (Cu), max. | 0.25% | 0.25% |
| Iron (Fe), max. | 0.40% | 0.40% |
| Manganese (Mn), max. | 0.35% | 0.35% |
| Carbon (C), max. | 0.15% | 0.02% |
| Silicon (Si), max. | 0.35% | 0.35% |
| Sulfur (S), max. | 0.01% | 0.01% |
B160 acceptance minimums appear below for hot-worked, cold-worked, and annealed bar, in both unit systems. However, the requirements shift with condition and section size, so the table separates them.
| Grade / Condition | 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, 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, 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 diameters or cross sections under 2.4 mm (3/32 in.). Hot-worked bar ships to the B160 condition that matches the ordered section.
Values below describe annealed material at room temperature and serve design work rather than acceptance. Notably, the two grades part company on thermal conductivity and electrical resistivity.
| Property | Nickel 200 (N02200) | Nickel 201 (N02201) |
|---|---|---|

B160 is the governing specification for both grades, and it sets the mechanical requirements by condition and section. For acceptance, an ASTM International standard named on the order decides.
| Standard / Designation | Scope |
|---|---|
| ASTM B160 / ASME SB160 | Rod and bar — UNS N02200 and UNS N02201 |
| DIN 17752 / ISO 9723 | Nickel bar and rod |
| DIN 17740 | Wrought nickel — chemical composition |
| VdTÜV 345 | Wrought nickel — technical delivery conditions |
| JIS G 4904 | Nickel and nickel alloy bar |
| W.Nr. 2.4066 / 2.4068 | European designations for Nickel 200 and Nickel 201 |
| UNS N02200 / N02201 | Material designations for the two grades |
Two limits belong with this table. ISO 9724 and DIN 17753 cover wire rather than bar, so neither applies to a bar and rod order. In addition, AMS 5553 covers low-carbon sheet and strip alone, which leaves Nickel 200 without an aerospace material specification and puts plate, bar, and tube outside its range.
Diameters, sections, and lengths below cover the ranges normally produced to B160. Nevertheless, condition and finish shift what we can quote, so we confirm every size at quotation.
| Product Form | Typical Supply | Length |
|---|---|---|
| Round Bar | 6–500 mm dia. | Cut to length or random |
| Round Rod | 3–50 mm dia. | Cut to length |
| Bright Bar | 6–150 mm dia. | Cut to length or random |
| Square Bar | 10–150 mm | Cut to length or random |
| Hex Bar | 10–150 mm across flats | Cut to length or random |
| Flat Bar | 3–100 mm thick × 10–300 mm wide | Cut to length |
| Forged Bar | 100–500 mm dia. or forged section | Cut to length |
| Centreless Ground Rod | 3–100 mm dia. to close tolerance | Cut to length |
Finish follows the operation that comes next, whether that is turning, grinding, or an as-supplied surface. In short, the ordered condition and finish decide what the line prepares.
| Surface Condition | Typical Use |
|---|---|
| Hot-worked | General service parts that will be machined to size |
| Annealed and pickled | Scale-free bar for fabrication and machining |
| Cold-drawn | Close diameter control with a smooth, bright surface |
| Peeled | Uniform diameter with a machined skin for further turning |
| Centreless ground | Tight diameter and straightness for shafting and spindles |
| Rough turned | Large or forged bar with a controlled machining allowance |

One contact carries a bar enquiry from the first question to loading. A quotation states the condition, tolerance, and test requirements in writing, so nothing rests on a verbal understanding.
Give the grade, standard, section, diameter, length, condition, and finish.
Then we check the ordered condition, tolerance, and finish against the production route.
We record the machining operation, straightness requirement, and any third-party witness point.
We send the price, the lead time, and the document list in one reply.
We fix the agreed section, condition, inspection level, and delivery terms before cutting.
The bar takes its working, heat treatment, and final test against the ordered standard.
Certificates, packing list, and shipping papers go out with the bar.
Feedback from buyers and engineers who source nickel alloy materials from Southerly Alloy.
“The Nickel 201 bar for our caustic evaporator carried the low-carbon limit on the certificate, and the heat numbers matched our drawing.”
“We ordered both grades on one purchase order and received separate certificates for UNS N02200 and UNS N02201.”
“Diameter and straightness on the centreless-ground rod stayed inside tolerance, so our shafting needed no rework.”
Our production and inspection processes are certified to international standards, and every delivery ships with EN 10204 3.1 mill test certificates.

ASTM B160, and its ASME edition SB160. Both grades appear in that one standard, so a mixed order needs no separate specification.
No. ISO 9724 and DIN 17753 cover wire, so a bar order quotes against DIN 17752 and ISO 9723 alongside B160.
Choose cold-worked bar where strength matters as supplied, and annealed stock where the part needs heavy machining or forming. Hot-worked bar suits parts that will be machined all over.
One piece covers many common sizes. Also, we accept trial quantities on the same terms as full orders, so a first order can stay small.
Most quotations stand on FOB terms. Additionally, we quote EXW or CIF when you prefer one of them, and we name the port at quotation.
Weight drives the figure, with the nickel price fixed on the quotation date. Section, condition, finish, and quantity each move the final number.
Stock sizes dispatch within 7–15 days of confirmation. Then made-to-order sections take about 25 days, and we state the date in writing.
Every bar carries an EN 10204 3.1 mill certificate. We arrange a 3.2 endorsement through a third party when your project asks for it.
Above about 315 °C in continuous service, where graphite leaves solution along the grain boundaries of grade 200 and embrittles the part.
Yes. Also, we cut to your length, draw, peel, or grind to your diameter, and quote the tolerance with the price.
Send the grade, section, diameter, length, quantity, condition, and finish. We reply with the price, the delivery date, and the document list in one message.
Stock sizes cover many common sections, and made-to-order drawing handles the rest. Therefore, a trial bar is a practical way to check finish before a full order.
