GL EH40 shipbuilding steel plate and sheet

GL EH40 Steel Description:
The steel for shipbuilding and oil platform---EH40, is the high tensile strength steel.
GL EH40 is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.GL EH40 steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.
GL EH40 Steel Application :
GL EH40 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.

GL EH40 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	Nb	V
GL EH40	0.18	0.50	0.90-1.60	0.035	0.035	0.015	0.02	0.35	0.20	0.40	0.08	0.02-0.05	0.05-0.10

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

GL EH40 Steel Mechanical properties:

Grade	Rm (MPa)	Re(MPa) min	A% min	Akv/J min
GL EH40	510-660	390	20	E.T °C	Thickness (mm)
				0	≤ 50		>50-70		>70-100
					L	C	L	C	L	C
					41	27	-

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

GL EH40 Steel Delivery state:

Grade	Fine grains elements	category	The thickness of steel
			≤ 12	>12.5-20	>20-25	>25-35	>35-50	>50-100
GL EH40	any	Plate/ sheet	N(50),CR(50),TM(50)					-
		Profile steel

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.

Shipbuilding steel,generally speaking,a hull structure steel , is to manufacture hull as the requirements of register of shipping. 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. With excellent welding performance,so a variety of welding method can be used for welding . GL EH40 has little alloy elements and grain refinement elements added, so its weldability is good.
