| Abstract: | The effects of tempering temperature on structure and property of X70 pipeline steel after induction bends were studied by the methods of thermal simulation, mechanical property testing and metallographic examination. And the structure and property of the steel processed with thermal deformation, different cooling rate and tempering was compared with that without tempering treatment. The importance and the best parameter range of tempering tem- perature for X70 pipeline steel after induction bends were defined. |
