X70 steel plate/pipes,under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of steel for large diameter pipes, API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is 570 MPa). It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.
