NK E   

NK E Shipbuilding steel plate
NK E steel for shipbuilding is not only the common tensile strength steel but also is the Hull structural steel with good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and good welding properties.Shipbuilding steel grade NK E is used for shipbuilding and oil platform purpose and they are approved by NK and other classification societies.What's more,the NK E shipbuilding steel NK E 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.
