What is LR FH32 steel plate?

LR FH32 steel plate for shipbuilding&platform. The shipbuilding steel plate grade FH32 is the high tensile strength steel. FH32 shipbuilding steel is the Hull structural steel,with it’s good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.

 

LR FH32 Shipbuilding Steel Application:

LR FH32 Shipbuilding steel plates can be used for producing container and bulk cargo vessels as well as cruise ships, ferries and yachts. LR FH32 Shipbuilding steel plates are mainly used for making the hull of ship building and ship repairing, the offshore oil drilling platform, the platform pipe joints and other components.
