X70 steel coils of acicular ferrite microstructure for large diameter pipes were researched and developed at Baosteel. The products have been used in West East Gas Pipeline Project. Compared to the X70 of ferrite and pearlite microstructure, the newly developed X70 has high strength, high toughness, low transition temperature and high dynamic tear-resistance. The excellent properties of this steel are resulted from ultra-low carbon acicular ferrite with interaction of very fine precipitated particles and high-density dislocation.
