DH36 shipbuilding steel plate  is used for shipbuiling&platform.The shipbuilding steel plate grade DH36 is the high tensile strength steel.DH36 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. ASTM A131 DH36 steel plate  can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.

ABS DH36 Shipbuilding Steel Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

ABS DH36 Shipbuilding Steel Application:
ABS 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.
