The SEM micrograph of X70 steel revealed the presence of polygonal ferrite/pearlite banding (pancake type),an occurrence in hot-rolled,low alloy steels and a ferritic grain size.The presence of a small volumetric fraction of bainite / degenerated pearlite and the absence of acicular ferrite in X70 steel was also noted.Microstructure and mechanical properties of two Api steels X70 steel presented a lower ferritic grain size (ASTM 11 to 15) than X60 steel (ASTM 8 to 10) 19.This is a consequence of the well-known beneficial presence of microalloying elements (Nb and Ti) and the rolling parameters employed in the X70 steel thermomechanical processing 20-23 .Microstructure and Properties of Low Manganese API X70 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.The AF predominant microstructure is fine,homogeneous and free of band structure of hard phase.
