Tempering microstructure and mechanical properties of pipeline steel X80
Transactions of Nonferrous Metals Society of China, 2009 The tempering microstructure and mechanical properties of X80 steel used for heating-bent pipe were analyzed. The results show that the microstructure of X80 steel tempered at 550 ℃ and 600 ℃ is bainitic ferrite (BF)+granular bainite (GB), and partial ferrite laths in BF merge and broaden.
