The Charpy impact properties of high strength pipeline steel with different microstructure were investigated.Experimental results show that the high strength pipeline steel with acicular ferrite microstructure has higher ability to prevent impact cracking than that with ferrite pearlitic microstructure.It can be concluded that the excellent impact toughness of high strength pipeline steel with acicular ferrite microstructure can be obtained by strictly controlling inclusions and producing fine,homogeneous ferrite grains,M-A structure and precipitates.
