NV D36 hull steel plate

NV D36 steel plate for shipbuiling&platform.The shipbuilding steel plate grade NV D36 steel is the high tensile strength steel.NV D36 shipbuilding steel is the Hull structural steel,with good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. NV D36 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.
