Q345R vessel plate, Q345R steel plate, Q345R vessel steel steel plate

Q345R steel is known as Q345R vessel plate, Q345R steel plate, Q345R vessel steel. According to the new classification of GB 713-2008 Steel Plates for Boilers and Pressure Vessels implemented on September 1, 2008, 16MnG, 16MnR and 19MnG were merged into Q345R vessel steel.

Q345R vessel steel is a common low-alloy steel, is a boiler and pressure vessels commonly used steel. Delivery status of Q345R vessel plate: hot-rolled or normalized. The properties of Q345R vessel plate are similar to those of Q345 (16Mn) (16mm steel plate with yield strength greater than 345Mpa). The tensile strength of Q345R vessel plate is 510-640Mpa, the elongation of Q345R vessel plate is greater than 21%, and the zero V impact energy of Q345R vessel plate is greater than 34J. The process reference standard of Q345R vessel plate is GB713-2008.

Q345R vessel plate characteristics:
Q345R vessel plate is special plate for pressure vessel with yield strength of 340 MPa. Q345R vessel plate has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R vessel plate is slightly lower than that of low alloy high strength steel Q345 (16Mn). The tensile strength and elongation of Q345R vessel plate are higher than that of Q345 (16Mn) steel, and the impact toughness Q345R vessel plate is also required. Q345R vessel plate is the most widely used pressure vessel special steel plate in China.
