| Abstract: | The properties of Q960E steel 70 mm plate quenched at 890-920 °C and tempered at 560-600 °C are tested, and the microstructure of Q960E steel is analyzed by metallographic microscope (OM) and scanning electron microscope (SEM) . The results show that the strength toughness matching of the steel plate is the best when quenching at 920 ℃ and tempering at 560 °C (UTS 1 048 MPa,YS 1 005 MPa, e1.14% and -40 °C KV2 52-61 J), the performance distribution of the steel plate in the full thickness direction is relatively uniform, and the hardness value is 27.5-33HRC, the microstructure from the surface to the center is tempered sorbite and residual austenite. |
