    Q235 vs. Q345 Steel Plate (How to Distinguish q235 vs q345 steel chemical composition

    Q235 is different from Q345s carbon content, and its chemical content is different. (this is a foolproof method) The distinction between Q235 and Q345 is made by welding: the two steel plates of unknown materials are welded together with ordinary welds, and the steel plates with cracks are shown as Q345 materials. (this is practical experience)Q345 Steel Specification and Equivalent StandardApplication difference Q345 - Q235: As Q345 and Q235 alloy element content is different, their applications are quite different.
