Properties
| 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 | 750 – 950 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.
