This is higher than that observed at 20°C (though the stress redistribution at this temperature remains highly significant), but as the temperature increases further, so the magnitude of the stress redistributed during the hold period diminishes such that once a temperature of 230°C is considered, the stresses at the beginning and end of the load hold are largely the same.
