AH36 shipbuilding steel plate through the quality certification

AH36 shipbuilding steel plate

AH36 steel is a kind of high tensile strength steel for shipbuilding. Our AH36 shipbuilding steel plates are certified by Lloyds Register of Shipping, but a number are also classified by DNV.
Size range of AH36 shipbuilding steel plate:
Thickness: 5 – 150 mm
Widths: 1500 – 3000mm
Lengths: 6m, 12m and 14m, or according to customers’ requirement
Chemical composition of AH36 shipbuilding steel plate Max (%):

Grade	C	Si	Mn	P	S	Al min	Ti	Cu	Cr	Ni	Mo	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.
