Mechanical and Metallurgical Properties of Grade X70 Steel

The influence of composition and microstructure on susceptibility to hydrogen induced cracking (HIC) was investigated in high strength pipeline steels,with Mn contents of 1.2% (standard,X70 Microstructure and Mechanical Properties of Two Apiassociated with banding).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 processing20-23.Its interesting to note the Microstructure and mechanical property improvement ofExperimental test reveals that in asymmetry condition in TMR process of X70,increase of the speed ratio (1.021.05) in roughing passes leads to a considerable grain refinement and growth of yield strength and ultimate tensile strength of 3.12 and 2.05% of final plate structure,respectively.
