DNV EH32  Steel Description:

The steel for shipbuilding and oil platform---EH32, is the high tensile strength steel.
It is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.

DNV EH32 Steel Application :

DNV EH32 steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.DNV EH32 is mainly used to manufacture  the ship hull structure of ocean, coastal and inland sea areas , shipyards, oil platforms, pipelines in the ocean, coastal power plants, port facilities and other structural parts.

DNV EH32 is with excellent welding performance, a variety of welding method can be used for welding . EH32  has little alloy elements and grain refinement elements added, so its weldability is good . Shipbuilding steel includes four grades,that is A,B,C,D. Grade A means impact test at 20°C; Grade B is impact test at 0°C; Grade C means impact test at -20°C; Grade D is impact test at -40°C. Our steel has exported to many countries ,like Korea,Viet Nam,Singapore,etc,and has a good reputation in the world.
