LR DH36 shipbuilding steel plate

LR DH36

LR DH36 steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.LR DH36 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 LR DH36 shipbuilding Steel offered by JoinWin Industry can be certificated by JoinWin as per customer's request.

Key words: LR DH36 shipbuilding steel, LR DH36 Ocean steel, LR DH36 Marine steel,LR DH36 offshore engineering steel. LR/DH36 shipbuilding steel, LR/DH36 Ocean steel, LR/DH36 Marine steel

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
DH36	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.
