NV E steel plate is the mainly kinds of steel for shipbuilding and oil platform, the shipbuilding grade NV E steel can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons. Shipbuilding grade NV E steel is the high tensile strength steel, NV E steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
