DNV EH32

DNV EH32 shipbuilding steel plate and sheet

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 Steel chemical composition by [%]:

Grade	C max	Si max	Mn	P max	S max	Als min	Ti max	Cu max	Cr max	Ni max	Mo max
DNV EH32	0.18	0.50	0.90-1.60	0.035	0.035	0.015	0.02	0.35	0.20	0.40	0.08

Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100).
Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

DNV EH32 Steel Mechanical properties:

Grade	Rm (MPa)	Re(MPa) min	A% min	Akv/J min
DNV EH32	440-570	315	22	E.T °C	Thickness (mm)
				-40	≤ 50		>50-70		>70-100
					L	C	L	C	L	C
					31	22	38	26	46	31

Note: In the list , Rm: .tensile strength,Re: Yield strength,A%: elongation, E.T: experimental temperature,L: lengthways, C: crosswise.

DNV EH32 Steel Delivery state:

Grade	Fine grains elements	category	The thickness of steel
			≤ 12	>12.5-20	>20-25	>25-35	>35-50	>50-100
DNV EH32	Any	Plate/sheet	N,TM
		Profile steel	N(25),TM(25),AR(15),CR(15)					-

Note:
1. delivery condition: A =Any ; N=Normalized ; CR=Control Rolled ; TM=TMPC, Temperature - deformation control rolling; AR*= Can be hot rolled with the agreement of Classification Society ; CR*=Can be control rolled with the agreement of Classification Society .
2. The Figure in the ( ) means the sampling volume to do the impact test, the unit is Ton.(-) means without impact test.

Contrast in the different standard

ASTM A131M	TOCT 5521	JIS G3106	BS LR	GB712
EH32	E32	SM490B SM490C	EH32	E32

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.
