LR DH40 shipbuilding steel description
LR DH40 steel plate for shipbuilding&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.
LR DH40 shipbuilding steel application range
LR 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, LR DH40 shipbuilding steel is widely used in oil platform and offshore platform.
