Grade A shipbuilding steel is a kind of shipbuilding steel which is usually used for shipbuiling&platform. Grade A steel is the common tensile strength steel. It is the Hull structural steel. For example, ASTM A131 A shibuilding steel plate, 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.

Grade A shipbuilding steel Main features:Good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.
