Q345A Carbon Steel Round Bar
Q345A Round Bar Products Description
The grade of Q345A round stock metal indicates: Q stands for yield strength; 345 stands for yield point value (in MPa); the letter A stands for low temperature impact resistance, and Q345A round bar does not undergo impact.
Q345A steel round bar adds microalloying elements V, Ti, and Nb, refines the grains, improves the toughness and comprehensive mechanical properties of Q345A round stock steel, and allows for greater thickness.
