NK D32

NK D32 Shipbuilding steel plate
NK D32 steel for shipbuilding is not only the high tensile strength steel but also is the Hull structural steel with good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and good welding properties.Shipbuilding steel grade NK D32 steel is used for shipbuilding and oil platform purpose and they are approved by ABS,DNV,GL,BV,LR,NK,RINA and other classification societies.What's more, NK D32 shipbuilding steel plate can be used in manufacturing the ship's hull structure whose weight is below 10000 tons.
NK D32 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
NK D32	0.18	0.50	0.90-1.60	0.035	0.035	0.015	0.02	0.35	0.20	0.40	0.08

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.
