LR A shipbuilding steel description

LR A steel plate for shipbuilding&platform. The shipbuilding steel plate grade A is the common tensile strength steel. LR A shipbuilding steel is the Hull structural steel, with it's good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.

LR A shipbuilding steel application range

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