NK A36

NK A36 Shipbuilding steel plate
NK A36 steel plate, NK A36 steel is a kind of steel for shipbuilding and platform.Shipbuilding steel plate NK A36 is the high tensile strength steel.As a professional shipbuilding steel plate exporter, Bebon international can supply steel plate NK A36. NK A36 shipbuilding steel plates can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons.

NK A36 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	Nb	V
NK A36	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 : ≤ 0.38% (thickness ≤ 50mm),≤0.40%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
