Title: Quenching and Tempering Technology of Q960 Steel Used for Engineering Machinery
Abstract: To develop Q960 steel plates used for engineering machinery,heat treatment technologyies of quenching and tempering was studies.The results show that the optimum quenching technology was heating at 900 ℃ for 20 min,and the optimum tempering technology was heating at 600 ℃ for 40 min.The microstructure of tested steel was temper sorbit after optimum quenching and tempering heat treatment,and yield strength,tensile strength,elongation and impact energy at-40 ℃ respectively was 1 030 MPa,16.8% and 144 J,they could meet the acquirement of GB/T 16270-2009.
