NK Grade E shipbuilding steel plates also can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components. The NK Grade E shipbuilding steel plate
is certified by NK –Nippon Kaiji Kyokai.NK Grade E shipbuilding steel plate is a kind of hot rolled general tensile strength steel.
NK Grade E shipbuilding steel plate are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment.
