GL FH36 Steel Description:
The steel for shipbuilding and oil platform---FH36, is the high tensile strength steel.
GL FH36 is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.Shipbuilding steel,generally speaking,a hull structure steel , is to manufacture hull as the requirements of register of shipping.

GL FH36 Steel Application :
GL FH36 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 FH36 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 FH36	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 :
≤ 0.38% (thickness ≤ 50mm),≤0.40%( when the thickness >50-100).
Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

GL FH36 Steel Mechanical properties:

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

GL FH36 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 FH36	Any	Plate/sheet	N,TM,Q&T
		Profile steel	N(25),TM(25),Q&T(15),CR*(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.

GL FH36 steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons. GL FH36 is with excellent welding performance, a variety of welding method can be used for welding . FH36 has little alloy elements and grain refinement elements added, so its weldability is good .
