A131 AH40 steel plate for shipbuilding&platform.The shipbuilding steel plate grade AH40 is the high tensile strength steel.AH40 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.ASTM A131 AH40 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.
AH40 ship steel plate specification:
Thickness: 3mm to 300mm,
Width: 1500mm to 4200mm
Length: 3000mm to 18000mm.
AH40 ship steel plate application:
A131 AH40 with the low temperature impacting test at zero centi-degree. For these three steel grades, they have the same chemical composition and the big difference is their yield and tensile strength.
