FH32 shipbuilding steel plate for shipbuiling&platform.The shipbuilding steel plate gradeFH32 is the high tensile strength steel. FH32 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. ASTM A131 FH32 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.

FH32 Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm,
Length: 3000mm to 18000mm.

FH32 shipbuilding steel plate Chemical Composition %

Grade	C max	Si max	Mn	P max	S max	Als min	Ti max	Cu max	Cr max	Ni max	Mo max	N max
FH32	0.16	0.50	0.90-1.60	0.025	0.025	0.015	0.02	0.35	0.20	0.80	0.08	0.009

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.
