摘      要：The production of Q&T line pipe steels for heavy wall pipe requires several properties to be fully *** them is the yield strength for strain based criteria pipelines for subsea *** strength must match the required minimum under elevated temperature conditions [60 & 160 ℃] and at the same time do not exceed the surface hardness that will make the welding *** of 220 vickers hardness has been set for some of the subsea *** in a busy Q&T line requires simple tools to predict the time and temperatures to achieve the desired *** classical strength and logarithm of time,after Bhadeshia [1],has been used with excellent results in these line pipe steels of different wall thickness.
