NV F32 Shipbuilding steel plate
NV F32 steel plate for shipbuiling&platform.The shipbuilding steel plate grade NV F32 is the high tensile strength steel.NV F32 shipbuilding steel is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.NV F32 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.
NV F32 steel plate Chemical Composition %
| Grade | C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr
