which grade is better 16mn or q345r
Dec 12, 2019 · The chemical element is similar to 16Mn, and Q345 increases the micro-alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steel, thus allows a greater thickness. Therefore, the mechanical performance of Q345 steel is better than that of 16Mn steel, especially its low-temperature performance. Q345 Chemical composition, Q345 Properties - Steel gradesThis page cover the Mechanical Properties, Chemical Element, Cross Reference of China GBT Q345 steel grade, Application China structural steel and alloy steel,
