The size, shape, weight and allowable deviation of Q390D, Q390D-Z35 steel plate should comply with the provisions of GB/ T709-2016. The maximum thickness of the steel plate is 135mm. When the BV EH40 hull steel plates, Q390D steel, Q390D-Z35 plate thickness is less than 100 mm, the required performance level in the thickness direction is z25; when the thickness is ≥ 100 mm, the required performance level in the thickness direction is Z35, which shall specifically comply with the provisions of GB/T5313-2010.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest BV EH40 hull steel plates processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain BV EH40 hull steel plates by rolling method.
