【Abstract】 Synopsis:This paper describes the property requirements of high grade pipeline steel and discusses the effect of elements, such as C,S,P,O,Mn,H 2, on the steel properties as well as the control of the elements. The integration of compositions adjustment,metallurgical technology and TMCP can be considered the key poinst to develop high grade pipeline steels. A gap in high grade pipeline development between China and developed countries and the trend of its development are also reviewed in the paper.更多还原
