LR AH40 shipbuilding steel description

LR AH40 steel plate for shipbuilding&platform. The shipbuilding steel plate grade AH40 is the high tensile strength steel. AH40 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties, and welding properties.

LR AH40 shipbuilding steel application range

LR AH40 shipbuilding steel can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons, and usually do navigation around coastal and river area. Also, LR AH40 shipbuilding steel is widely used in oil platform and offshore platform.

LR AH40 shipbuilding steel 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
AH40	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 : ≤ 0.36% (thickness ≤ 50mm), ≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
