NV A Shipbuilding steel plate
NVA steel plate for shipbuiling&platform.The shipbuilding steel plate NVA Steel plate is the common tensile strength steel.NV A shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. NV A steel plate can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons,and usually do navigation around coastal and river area.
