Choose Nickel 200 when
The governing specification or engineering design explicitly calls for UNS N02200 and service temperature does not create the low-carbon requirement.
Buyer comparison guide
Nickel 200 vs Nickel 201
The central purchasing difference is carbon control. Nickel 201 limits carbon more tightly and is normally considered when prolonged elevated-temperature exposure makes graphitization a concern.
Confirm the required grade, product standard, condition and test documentation on the purchase order.Side-by-side
Procurement comparison
Both grades are commercially pure wrought nickel. They share many corrosion and fabrication characteristics, but they should not be substituted without reviewing temperature, governing specification and design requirements.
| Buyer question | Nickel 200 | Nickel 201 |
|---|---|---|
| UNS / W.Nr. | N02200 / 2.4066 | N02201 / 2.4068 |
| Carbon limit | 0.15% max | 0.02% max |
| Typical selection emphasis | General commercially pure nickel service | Low-carbon grade for elevated-temperature consideration |
| Common forms | Sheet, plate, strip, bar, wire, tube | Sheet, plate, strip, bar, wire, tube |
| Plate/sheet/strip reference | ASTM B162 | ASTM B162 |
| Rod/bar reference | ASTM B160 | ASTM B160 |
Selection logic
Which grade should a buyer specify?
The drawing, process conditions and applicable code control the decision. The points below help prepare a technically complete inquiry.
Evaluate Nickel 201 when
Prolonged service above about 315°C is expected, or the drawing and applicable specification require UNS N02201.
Do not select by price alone
Confirm carbon limit, mechanical condition, dimensions and certification before comparing offers.
State the exact form
A bar inquiry and a thin-strip inquiry follow different production routes, tolerances and minimum quantities.
