The GB713 Q345R steel plate is a pressure vessel special plate with a yield strength of 345 MPa, which has good comprehensive mechanical properties and process properties. The phosphorus and sulfur content of GB71 Q345R steel plate is slightly lower than that of low alloy high strength steel plate Q345(16Mn) steel. In addition to the increase of tensile strength and elongation requirement than Q345 (16Mn) steel, it is also required to ensure the impact toughness of GB71 Q345R steel plate. GB71 Q345R steel plate is the most widely used steel pipe for pressure vessels in China.
