RINA DH40 shipbuilding steel description

DH40 steel plate for shipbuiling&platform. The shipbuilding steel plate grade DH40 is the high tensile strength steel. DH40 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties, welding properties and so on.

RINA DH40 shipbuilding steel application range

RINA DH40 shipbuilding steel can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons, and usually do navigation around coastal and river area. Also, RINA DH40 shipbuilding steel is widely used in oil platform and offshore platform.

RINA DH40 shipbuilding steel 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 : ≤ 0.36% (thickness ≤ 50mm), ≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15
