Study on Improving the Performance of X80 Pipeline Steel

This paper analyzes the methods of improving the performance of X80 pipeline steel. In the process of manufacturing piping, the right temperature of coiling the steel can improve the comprehensive mechanical properties of X80 pipeline steel. The proper cooling rate can make heat affected zone get the good performance. Quenching can improve the performance of X80 pipeline steel, but the temperature can not be too high. At the same time, the appropriate tempering treatment can make X80 pipeline steel obtain good hardness, strength, plasticity and toughness.
