DNV Grade D steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels,ship body construction.Normally when rolling,Air rolled and Control Rolled is ok for ship plate DNV Grade D with the thickness equal and belows 40 Millimeters,and for thickness above 40mm,the heat treatment shall be Normalised or TMCP,these two technical treatment would improve steel strength in yield and tensile points for shipbuilding steel plate DNV Grade D.


Xinsteel owned tens of stock warehouses at Shanghai,Tianjin port and Zhengzhou inner city which store thousands tons of shipbuilding steel plate with many grades,such as DNV Grade B,DNV Grade A,DNV Grade D,DNV Grade E and higher ship steel grades DNV Grade DH36,DNV Grade EH36 and DNV Grade FH32.Please send your needed sizes and steel grades to us if you demand of stock of shipbuilding steel plate.
