ASTM A131 AH36 Shipbuilding steel plate

AH36 shipbuilding steel plate specification:

Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

AH36 steel Chemical Composition %:

 

Grade	C max	Si max	Mn	P max	S max	Als min	Ti max	Cu max	Cr max	Ni max	Mo max	Nb	V
AH36	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.

 

AH36 steel plate Mechanical Property

 

Grade	Rm (MPa)	Re(MPa) min	A% min	Akv/J min
AH36	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.

 

AH36 steel plate Condition Of Delivery

 

Grade	Fine grains elements	category	The thickness of steel
			≤ 12	>12.5-20	>20-25	>25-35	>35-50	>50-100
AH36	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.

 

ASTM A131 AH36 Shipbuilding steel plates are often used in the marine engineering manufacturing industry, such as shipbuilding, marine engineering, offshore platform construction, cross-sea bridge leg piles, pillars, and derricks.
