The FH40 steel plate is mainly used for shipbuilding and oil platform, the shipbuilding grade FH40 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons. Shipbuilding grade FH40 is the high tensile strength steel, FH40 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
FH40 Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
