DNV Grade D620,NV D620

Ship steel plate DNV D620 is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.Shipbuilding steel plate DNV D620 mainly be used in about minus 20 centigree ocean situiation. NV D620 steel plate is done low temperature impacting test when rolling in our steel mill.Xinsteel are rolling thousands tons of shipbuilding plate DNV D620 with DNV agency endorsed and stamped every month,and transported to domestic shipyards to use and export to overseas shipyards.
