Abstract The production technology and mechanical properties of X65 pipeline steel plate produced by 3500 steckel mill at Nanjing Iron & Steel United Co. are introduced. The results show that using TMCP technology, the X65 pipeline steel plate produced can obtain an acicular ferrite microstructure and strength and toughness equal to that of X70 steel. In X65 steel the content of Nb, Ti and Mo should be reasonable, C content must be less than 0.07%, P and S less than 0.013% and 0.002% respectively. In addition, X65 steel has good weldability.

Key words： X65 pipeline steel steckel mill product development microstructure property
