GL AH36TM

GL AH36TM shipbuilding steel plate and sheet

GL AH36TM Steel Description:
The steel for shipbuilding and oil platform---AH36TM, 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.This kind of steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.
GL AH36TM Steel Application :
GL AH36TM is with good mechanical properties, welding performance, process performance. GL AH36TM 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 AH36TM 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 AH36TM	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 : ≤ 0.38% (thickness ≤ 50mm),≤0.40%( when the thickness >50-100).
Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

As for AH36TM, if the thickness is under 12.5mm, the minimum Mn is about 0.7%. Besides, aluminum, niobium or vanadium in which one or several elements of grain refinement elements should be added to AH36TM Steel.

GL AH36TM Steel Mechanical properties:

Grade	Rm (MPa)	Re(MPa) min	A% min	Akv/J min
GL AH36 TM	490-630	355	21	E.T °C	Thickness (mm)
				0	≤ 50		>50-70		>70-100
					L	C	L	C	L	C
					34	24	41	27	50	34

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

GL AH36TM 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 AH36TM	Nb+V or V	Plate/ sheet	A(50)	N(50),CR(50),TM(50)					N(50),CR(25),TM(50)
		Profile steel		N(50),CR(50),TM(50),AR*(25)					-
	Al or Al+Ti	Plate/ sheet	A(50)		AR*(25)			-
					N(50),CR(50),TM(50)				N(50),CR(25),TM(50)
		Profile steel	A(50)	N(50),CR(50),TM(50),AR*(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. 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. GL AH36TM shipbuilding plate has low alloy content, grain refinement elements like V, Ti, Nb, etc. Welding performance is superior. If you are interested in the steel,please contact us at any time.
