LR FH40 shipbuilding steel description

LR FH40 steel plate for shipbuilding&platform. The shipbuilding steel plate grade FH40 is the high tensile strength steel. FH40 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,welding properties and so on.

LR FH40 shipbuilding steel application range

With the super features of good toughness properties, higher strength,strong corrosion-resistance,the processing, FH40 steel plate/sheet widely used in the manufacture of the ship's hull structure, and usually do navigation around coastal and river area. Also, LR FH40 shipbuilding steel is widely used in oil platform and offshore platform.

LR FH40 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	N max
FH40	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 : ≤ 0.36% (thickness ≤ 50mm), ≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
