Abstract High temperature Mechanical properties of Q345E steel billet were tested on gleeble 3800 and deformed fracture mechanism was analysed by observing fracture morphology of the samples . The test results indicate that the brittle temperature zone of Q345E steel billet is 750��~900�� in the region of 600�� to 1300�棬and the plastic temperature zone is 950��~1300��.The results will provide theory data for the production of Q345E steel billet.
