Ship plate LR Grade A is the Hull structural steel, with it is good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
LR Grade A steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels, ship body construction. In the steel standard ASTM A131/A131M, offshore steel grade ASTM A131 Grade A is the best equivalent steel grade with LR Grade A.
