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.
