For decades years,Xinsteel is alway developing and rolling heavy steel plates,especially wide and heavy shipbuilding steel plate.In China stated owned steel mills,now just Xinsteel can roll DNV Grade FH32 shipbuilding steel plate with thickness above 100 millmeters.We can roll this steel grade DNVGrade FH32 reach to 350 millimeters.This is also the most heavy thickness in the world.Our steel plates have been approved by TUV from Germany and ABS from America and other international and domestic high honors.
Our engineers guarantee the steel property for rolling shipbuilding steel Grade FH32 with DNV ship surveyor approved.With alloy elements especially the element Nickel,DNV Grade FH32 shipbuilding steel plate can bear the weather corrosion when using to build ships and vessels.When rolling DNV Grade FH32 steel plate,the steel should be chosed as full killed and hot rolling.Normalized heat treatment have to be done when the steel billets finished.Low temperature impacting test should be made under minus 60 centigree.
