The mechanical properties of steel pipe have great effects on the integrality and operation safety of gas transmission pipeline. In order to reduce the cost of the steel pipe, the high-Nb X80 pipeline steels with the different alloying systems have been used in the Second West-to-East Gas Transmission Pipeline Project. Nevertheless, an investigation into the effects of chemical composition on Microstructure and Properties of Low Manganese API X70 Abstract. The microstructure and properties of a low manganese (0.91.0%Mn) X70 pipeline steel for sour service application was investigated. The microstructure of thermomechanically processed X70 pipeline steel primarily consisted of acicular ferrite (AF) together with small fraction of polygonal ferrite(PF), degenerated pearlite (DP) and martensite/austenite (M/A) constituent.
