LR D shipbuilding steel description:

LR D shipbuilding steel is a common tensile strength steel. D shipbuilding steel is the Hull structural steel which with a good toughness properties, higher strength,strong corrosion-resistance, the processing properties,and welding properties.

LR D shipbuilding steel Application range

LR D 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 D shipbuilding steel is widely used in oil platform and offshore platform.
