GL FH40TM

GL FH40TM shipbuilding steel plate and sheet

GL FH40TM Steel Description:
The steel for shipbuilding and oil platform---FH40TM, is the high tensile strength steel.
GL FH40TM is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.GL FH40TM steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.
GL FH40TM Steel Application :
GL FH40TM steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons. GL FH40TM 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 FH40TM 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	N max
GL FH40TM	0.16	0.50	0.90-1.60	0.025	0.025	0.015	0.02	0.35	0.20	0.80	0.08	0.02-0.05	0.05-0.10	0.009

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 FH40TM Steel Mechanical properties:

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

GL FH40TM 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 FH40TM	Any	Plate/sheet	N,TM,Q&T					-
		Profile steel	N(25),TM(25),Q&T(25)

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. GL FH40TM is with excellent welding performance, a variety of welding method can be used for welding .GL FH40TM has little alloy elements and grain refinement elements added, so its weldability is good .
