DNV DH40 shipbuilding steel plate

 DNV DH40

DNV DH40 steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.DNV DH40 Shipbuilding steel plates are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components. All the DNV DH40 shipbuilding Steel offered by JoinWin Industry can be certificated by JoinWin as per customer's request.

chemical composition in shipbuilding steel plate, angle steel bar, bulb flat bar, L section steel bar

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
DH40	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 : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100).

Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
