FH40 steel phaj feem ntau yog siv hauv nkoj tsim thiab roj platforms. Shipbuilding qib FH40 tuaj yeem siv los tsim cov qauv ntawm lub nkoj uas hnyav tshaj 10,000 tons. Shipbuilding qib FH40 yog lub zog tensile siab steel. FH40 steel siv nyob rau hauv shipbuilding thiab roj platforms yuav tsum muaj zoo toughness, siab zog, muaj zog corrosion kuj, kev ua tau zoo thiab vuam kev ua tau zoo.
