Grade A Steel Plate is used for shipbuiling's hull structure and platform. The Shipbuilding Steel Plate grade A is the common tensile strength steel. It has good toughness properties and higher strength, strong corrosion-resistance,the processing properties,and welding properties.ASTM A131 Grade A 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 shipbuiling steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
