Properties

The typical mechanical properties of Nickel® 270:

ConditionApprox. tensile strengthApprox. operating temperature
Annealed<450 N/mm² (<65 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
600 – 800 N/mm² (87 – 116 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.
