Pipeline steel is a kind of special steel used for oil and gas transmission,and its microstructure and properties are the focus of researchers.In this paper,the latest research results on the microstructure and properties of pipeline steel for oil and gas transmission were reviewed,and the effects on the microstructure and properties were summarized from two dimensions,i.e.,adding alloy elements and rare earths,and heat treatment.It is found that the addition of rare earth and alloy elements will have different effects on the properties of pipeline steel,and the different heat treatment processes of different steel grades also have different effects on the properties.Finally,the future development directions of pipeline steel are prospected.
