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.
