NK F32

NK F32 Shipbuilding steel plate
NK F32 steel plate for shipbuiling&platform.The shipbuilding steel plate grade NK F32 steel is the high tensile strength steel. NK F32 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. NK F32steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.
NK F32 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
NK F32	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.
