Nickel® 201
A commercially pure Nickel (typically 99.6% Nickel), Nickel 201 is essentially the same as Nickel 200, but with a lower carbon content to prevent embrittlement by inter granular carbon at temperatures over 315°C (600°F). Lower carbon content also reduces hardness, which makes it ideally suited for spinning and cold forming. It is also preferred to Nickel 200 for applications involving exposure to temperatures above 315°C (600°F).
Nickel® 201 is also known as Phyweld 201.
Available in all profile options

Properties
The typical mechanical properties of Nickel® 201:
| Condition | Approx. tensile strength | Approx. operating temperature |
|---|---|---|
| Annealed | <500 N/mm² (<73 ksi) | Tensile strength and elongation drop significantly at temperatures above 315 °C (600 °F). Service temperature is dependent on environment, load and size range. |
| Hard Drawn | 700 – 900 N/mm² (102 – 131 ksi) | Tensile strength and elongation drop significantly at temperatures above 315 °C (600 °F). Service temperature is dependent on environment, load and size range. |
The above tensile strength ranges are typical. If you require different please ask.
