What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel A573 Gr.70 steel and A517 Grade A steel comparison.
