12Cr1MoV 13CrMoV4.2 steel plate/pipes, 12Cr1MoV steel plate/pipes, under DIN standard, we can regard 12Cr1MoV steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,12Cr1MoV steel with the demands in mechanical properties of the pipes followed the API specification for grade12Cr1MoV (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.
