Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. S690QL high strength steel plates, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.

The correct choice of billet type, section shape, size and weight are of great significance to S690QL high strength steel plates steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The S690QL high strength steel plates rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
