Microstructures and Properties of X60 Grade Pipeline Strip Steel in CSP Plant

The microstructures and properties of X60 grade pipeline strip steel were researched. With Nb microallo-ying and TMCP, the X60 grade pipeline strip steel was developed in the Baotou CSP Plant. The mechanical properties meet the demands on machining and using of pipeline manufacture. The X60 strip steels had been used extensively, which had fine and uniform structures, good performance and excellent toughness.
