CCSA CCSB AH32 shipping building steel plate
Specification
Ah32 steel plate is used for shipbuiling&platform.The shipbuilding steel plate grade AH32 is the high tensile strength steel. Ah32 shipbuilding steel has good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. ASTM A131 Ah32 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.
AH32 Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
