180 mm high grade and thick FH785 offshore engineering steel was successfully developed

Recently, high grade FH785 offshore engineering steel with large thickness has been successfully developed. Steel used in marine engineering is the material premise of expanding marine space and developing marine resources, and also the material guarantee of enhancing marine national defense strength and safeguarding marine rights and interests. At present, the maximum thickness of FH785 offshore steel plate we can supply is 180mm, the yield strength is 785MPa, and the impact energy requires - 60℃ low temperature toughness.

Large thickness FH785 steel plate is a new type of environmental protection steel material for offshore engineering. FH785 offshore engineering steel has super strong impact resistance and super high strength, and its strength and toughness is twice as high as that of conventional offshore steel. Compared with other high-grade offshore steel, FH785 offshore steel plate is easy to be welded in the process of processing, which can also speed up the manufacturing process and reduce the processing cost. It is a hot direction of production and research in the same industry at home and abroad.

FH785 material and other high-grade heavy thickness offshore engineering steel are mainly used in offshore oil production platform, wind power installation ship and other large offshore equipment. With the deepening of the work area, marine equipment needs to withstand the severe service environment such as sea waves, ocean undercurrent, atmospheric erosion, so the thickness, strength and toughness of steel plate are gradually improved.
