LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS DH40 Shipbuilding steel plate

Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,ASTM A131 DH40 steel plate is a kind of steel for shipbuilding and platform.Shipbuilding steel plate DH40 is the high tensile strength steel. As a professional shipbuilding steel plate exporter, Bebon international can supply steel plate DH40. ASTM A 131 DH40 shipbuilding steel plates can be used in the manufacture of the ship s hull structure whose weight is below 10000 tons.

DH40 Shipbuilding Steel Specification:
Thickness: 4 mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

DH40 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
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 : ≤ 0.40% (thickness ≤ 50mm). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
