Bebon AH40 DH40 EH40 FH40 steel plates/sheets would be mainly used for building crane project in many shipyards,also would be used in building ice breaker owning to its minus 60 centidegreeimpacting test when rolling.
TheAH40 steel plate is the mainly kinds of steel for shipbuilding and oil platform, the shipbuilding grade AH40 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons. Shipbuilding grade AH40 is the high tensile strength steel, AH40 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
