Basically, if Nitinol is NOT constrained, then it should be safe to heat it to about 250C without ill-effect. If you heat it above that, you will observe an increase in the transformation temperature, which can be problematic in medical devices. If a component is heated while constrained, the maximum temperature is much lower, possibly as low as 60C if the contraint is severe and the Af temperature low: this will be manifested by a permanent change to the shape of the device.
