The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A573 Grade 58 65 70 hot rolled plate is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
BBN steel have a lot of advantages for A573 Grade 58 65 70 hot rolled plate steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.
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 A573 Grade 58 65 70 hot rolled plate, 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.
