ASTM A131 DH36 steel

DH36 is high strength shipbuilding steel. Shipbuilding steel generally refers to the hull structure steel and it refers to the steel used in the manufacture of hull structure according to the requirements of classification society rules. Shipbuilding steel is often used as a special steel orders, production, sales, usually including ship plate and profile steel, etc.

ASTM A131 DH36 ship plate physical review:

Shipbuilding steel delivery, it shall have the manufacturer marks or other physical objects. The detail is as below:

1,Approved by the classification society. The common classification societies are CCS,ABS,LR,BV, DNV,GL, NK,KR, RINA etc.

2,Using paint box or paste tag, Including technical parameters as:batch No, heat No, standard grade, length, width, thickness and so on.

3,Appearance is bright and clean smooth, without defects.

DH36 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
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 : ≤ 0.38% (thickness ≤ 50mm),≤0.40%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
